RESUMO
BACKGROUND: The established therapy of asthma might be supported by additional non-pharmaceutical measures, such as the Buteyko breathing technique (BBT); however, the available data are mixed. To clarify the effects of BBT in patients with asthma, we investigated whether it led to clinical improvements with correlation to functional parameters. METHODS: Using a randomized, controlled design, we studied two groups (n = 30 each) of patients with asthma under either BBT or usual therapy (UT) w/o BBT over a period of 3 months. The primary outcome comprised the voluntary control pause (CP) after 3 months, secondary outcomes an additional breathhold parameter, forced expiratory volume in 1 s (FEV1), capnovolumetry, exhaled nitric oxide (FeNO), Asthma Control Questionnaire (ACQ) and Nijmegen Questionnaire (NQ), and the use of medication (ß2-agonists; inhaled corticosteroids, ICS). RESULTS: CP showed significant time-by-group interaction [F(1,58.09) = 28.70, p < 0.001] as well as main effects for study group [F(1,58.27) = 5.91, p = 0.018] and time [F(1,58.36) = 17.67, p < 0.001]. ACQ and NQ scores were significantly (p < 0.05 each) improved with BBT. This was associated with reductions in the use of ß2-agonists and ICS (p < 0.05 each) by about 20% each. None of these effects occurred in the UT group. While FEV1 and the slopes of the capnovolumetric expiratory phases 2 and 3 did not significantly change, the capnovolumetric threshold volume at tidal breathing increased (p < 0.05) with BBT by about 10 mL or 10%, compared to baseline, suggesting a larger volume of the central airways. No significant changes were seen for FeNO. CONCLUSIONS: BBT was clinically effective, as indicated by the fact that the improvement in symptom scores and the small increase in bronchial volume occurred despite the significant reduction of respiratory pharmacotherapy. As the self-controlled Buteyko breathing therapy was well-accepted by the participants, it could be considered as supporting tool in asthma therapy being worth of wider attention in clinical practice. Trial registration Retrospectively registered on 10 March 2017 at ClinicalTrials.gov (NCT03098849).

BACKGROUND: COVID-19-related lockdowns and homeschooling have imposed a substantial burden on school-aged children and parents. Waldorf education is a reform-educational concept. Little is known about the situation of German Waldorf families under pandemic conditions. METHODS: A cross-sectional, online, parent-proxy survey was conducted regarding the third pandemic wave. The primary outcome was parents' support needs, assessed with questions from the German COPSY (COVID-19 and PSYchological Health) study; the secondary outcome was children's HRQoL (KIDSCREEN-10, proxy version). RESULTS: We analyzed questionnaires from 431 parents of 511 Waldorf students aged 7 to 17 years. While 70.8% of Waldorf parents (WPs) reported a general need for support in dealing with their children, 59.9% of COPSY parents (CPs) indicated this need. WPs' support needs in dealing with their children's academic demands were similar to CPs' needs but relatively higher in terms of dealing with emotions and moods, behavior, and relationships within the family. WPs sought support mainly from school and teachers (65.6%). Support needs were high, although WPs rated their children's HRQoL higher than CPs. CONCLUSIONS: Our results underline the substantial pandemic-related burden on families across school types. WPs participating in this survey gave evidence that supports should focus on academic demands as well as psychosocial issues.

Background: Chest compresses with mustard (MU) or ginger (GI) are a complementary treatment option for respiratory tract infections. However, little is known about their specific thermogenic qualities. This study examines the short-term effects of MU, GI, and chest compresses with warm water only (WA) on measurable and self-perceived body warmth in healthy adults. Methods: This was a single-center, randomized controlled trial with cross-over design (WA versus MU versus GI). 18 participants (23.7 ± 3.4 years; 66.7% female) received MU, GI, and WA in a random order on three different days with a mean washout period of 13.9 days. Chest compresses were applied to the thoracic back for a maximum of 20 minutes. The primary outcome measure was skin temperature of the posterior trunk (measured by infrared thermography) immediately following removal of the compresses (t1). Secondary outcome measures included skin temperature of the posterior trunk 10 minutes later (t2) and several parameters of self-perceived warmth at t1 and t2 (assessed with the Herdecke Warmth Perception Questionnaire). Results: Skin temperature of the posterior trunk was significantly higher with MU compared to WA and GI at t1 (p < 0.001 for both, primary outcome measure) and t2 (WA versus MU: p=0.04, MU versus GI: p < 0.01). Self-perceived warmth of the posterior trunk was higher with MU and GI compared to WA at t1 (1.40 ≥ d ≥ 1.79) and remained higher with GI at t2 (WA versus GI: d = 0.74). The overall warmth perception increased significantly with GI (d = 0.69), tended to increase with MU (d = 0.54), and did not change with WA (d = 0.36) between t0 and t1. Conclusions: Different effects on warmth regulation were observed when ginger and mustard were applied as chest compresses. Both substances induced self-perceived warming of the posterior trunk, but measurable skin temperature increased only with MU. Further research is needed to examine the duration of these thermogenic effects and how chest compresses with ginger or mustard might be incorporated into practice to influence clinical outcomes in respiratory tract infections.
RESUMO
OBJECTIVES: To compare the effects between warm water (WW) and ginger footbaths (WW+ginger) on sleep quality and warmth regulation in adults with self-reported insomnia symptoms. METHODS: A prospective randomized-controlled study in which 28 participants (mean age 50.9 years, 64.3% women, insomnia symptom duration 11.4 years) were randomized to receive WW (n = 13) or WW+ginger (n = 15) daily for 2 weeks. Treatment involved nightly footbaths (12 liters of 38-42 °C warm tap water, maximum duration 20 min) with and without topical ginger (80 g of powdered ginger rhizomes). MAIN OUTCOME MEASURES: The primary outcome measure was self-reported sleep quality (global score from Pittsburgh Sleep Quality Index, PSQI) at 2 weeks. Secondary outcomes included measures of insomnia severity (Insomnia Severity Index, ISI) and warmth regulation (Herdecke Warmth Perception Questionnaire, HWPQ and 24-hour distal-proximal skin temperature gradient, DPG). RESULTS: WW+ginger had no greater effect on PSQI (mean between-difference 0.0 [95% CI -3.0 to 2.9], Cohen's d=0.0) or ISI (-0.2 [-3.9 to 3.4], 0.0) than WW. Nor were there any significant differences in HWPQ perceived warmth (0.1 ≥d≥0.5) or DPG (0.1 ≥d≥0.4) between WW and WW+ginger. Both groups improved over time in PSQI (WW+ginger: d=0.7, WW: d=1.3) and ISI (WW+ginger: d=0.8, WW: d=1.0). Perceived warmth of the feet increased only in WW+ginger over time (d=0.6, WW: d=0.0). CONCLUSIONS: This dose of ginger (6.67 g/liter) did not have greater effects on sleep quality, insomnia severity or warmth regulation than WW. Considering effect sizes, costs and risks, the use of WW would be recommended over WW+ginger in this patient population.

BACKGROUND: An effective and well-tolerated topical treatment of Raynaud's phenomenon is needed. The aim of this pilot study was to determine change in skin temperature and self-reported warmth perception from topical rosemary essential oil in patients with systemic sclerosis and secondary Raynaud's phenomenon. PATIENTS AND METHODS: Twelve patients with progressive systemic sclerosis and Raynaud's phenomenon were consecutively enrolled in an open-label pilot study at a university outpatient rheumatology clinic. Each patient received an application of olive oil to both hands as a control and 3 h later an application of a 10% essential oil of Rosmarinus officinalis L. Clinical severity and subjective warmth perception were assessed; skin temperature was measured by infrared thermography. RESULTS: Skin temperature increased significantly after both olive oil and rosemary oil but differences between oils did not reach significance. Self-reported warmth perception increased after rosemary oil but not after olive oil. No adverse effects were observed. CONCLUSION: Topical rosemary essential oil increased warmth perception in patients with systemic sclerosis-related Raynaud's phenomenon but did not increase finger skin temperature more than the olive oil control.

OBJECTIVE: Warm footbaths infused with Sinapis nigra (mustard, or MU) or Zingiber officinale (ginger, or GI) are used for various thermoregulatory conditions, but little is known about how they are perceived by individuals, both short- and long-term. We analyzed the immediate and long-term effects of MU and GI on warmth and stimulus perception in healthy adults. METHODS: Seventeen individuals (mean age 22.1±2.4 years; 11 female) received three footbaths (mean temperature was 40 ± 0.2°C, administered between 1:30 and 6:30 p.m.) in a randomized order with a crossover design: 1. with warm water only (WA), 2. with warm water and MU, and 3. with warm water and GI. Warmth and stimulus perception at the feet were assessed at the 1st, 5th, 10th, 15th, and 20th minute of the footbaths, in the late evening (EVE), and the following morning (MG). We further assessed well-being (at EVE and MG) and sleep quality (at MG). The primary outcome measure was the warmth perception at the feet at the 10th minute of the footbath. RESULTS: At the 10th minute of the footbath, warmth perception at the feet was significantly higher with MU and GI compared to WA. The immediate thermogenic effects pointed to a quick increase in warmth and stimulus perception with MU, a slower increase with GI, and a gradual decrease with WA. Regarding the long-term effects, warmth and stimulus perception were still higher after GI compared to WA at EVE and MG. No differences were seen for general well-being and sleep quality. CONCLUSION: Thermogenic substances can significantly alter the dynamics of warmth and stimulus perception when added to footbaths. The different profiles in the application of GI and MU could be relevant for a more differentiated and specific use of both substances in different therapeutic indications.

OBJECTIVE: To analyze the thermogenic effects of footbaths with medicinal powders in oncological patients (ON) and healthy controls (HC). INTERVENTION AND OUTCOMES: Thirty-six participants (23 ON, 13 HC; 24 females; 49.9 ± 13.3 years) received 3 footbaths in a random order with cross-over design: warm water only (WA), warm water plus mustard (MU, Sinapis nigra), and warm water plus ginger (GI, Zingiber officinale). Warmth perception of the feet (Herdecke Warmth Perception Questionnaire, HeWEF) at the follow-up (10 minutes after completion of footbaths, t2) was assessed as the primary outcome measure. Secondary outcome measures included overall warmth as well as self-reported warmth (HeWEF) and measured skin temperature (high resolution thermography) of the face, hands and feet at baseline (t0), post immersion (t1), and follow-up (t2). RESULTS: With respect to the warmth perception of the feet, GI and MU differed significantly from WA (P's < .05) with the highest effect sizes at t1 (WA vs GI, d = 0.92, WA vs MU, d = 0.73). At t2, perceived warmth tended to be higher with GI compared to WA (d = 0.46). No differences were detected between ON and HC for self-reported warmth. With respect to skin temperatures, face and feet skin temperatures of ON were colder (at t0 and t1, 0.42 ≥ d ≥ 0.68) and tended to have diametrical response patterns than HC (ON vs HC: colder vs warmer after MU). CONCLUSION: Among adult oncological patients and healthy controls, footbaths with mustard and ginger increased warmth perception of the feet longer than with warm water only. The potential impact of regularly administered thermogenic footbaths over extended periods merits further investigation for the recovery of cancer-related sense of cold.

OBJECTIVES: To examine the effects of warm footbaths with thermogenic medicinal powders on vitality and heart rate variability in healthy adults. Intervention and Outcome. Seventeen healthy young adults (22.1 ± 2.4 years, 11 females) received three footbaths (WA: warm water only; GI: warm water and ginger; MU: warm water and mustard) in randomized order with a crossover design. We assessed vitality with the Basler Befindlichkeit questionnaire (BBS) and heart rate variability (HRV) before (t0), immediately after (t1), and 10 minutes following footbaths (t2). The primary outcome measure was self-reported vitality, measured via the BBS, at t1. RESULTS: The primary outcome measure, self-reported vitality, was higher after GI and tended to be higher after MU compared to WA with medium effect sizes (GI vs. WA, mean difference -2.47 (95% CI -5.28 to 0.34), p adj=0.048, d adj = 0.74), MU vs. WA, -2.35 (-5.32 to 0.61), p adj=0.30, d adj = 0.50). At t2, the standard deviation of beat-to-beat intervals (SDNN) of HRV increased, and the stress index tended to decrease after all three footbath conditions with small to medium effect sizes (0.42-0.66). CONCLUSION: There is preliminary evidence that footbaths with thermogenic agents GI and MU may increase self-reported vitality during a short-time period with a more pronounced effect with GI. After a short follow-up, all three conditions tended to shift the autonomic balance towards relaxation. Future research should investigate these effects in clinical samples with a larger, more diverse sample size.
RESUMO
BACKGROUND: Evidence supports the Buteyko breathing technique (BBT) as reducing medication and improving control and quality of life in adults with asthma, but having minimal impact on spirometry. For children with asthma, evidence addressing the utility of BBT is sparse. We evaluated the effectiveness of BBT in managing various aspects of asthma in children. METHODS: Thirty-two children with partly controlled asthma (age 6-15 years, 66% male) were randomized to either Treatment as Usual (TAU) or TAU combined with Buteyko training (Buteyko group, BG). Children in the BG received an intensive five-day training followed by three months of home practice. Primary outcome was bronchodilator reduction. Secondary outcomes were changes in physiological parameters FEV1_AR (at rest), FEV1_ER (after ergometry), FEV1_BR (after bronchospasmolysis), corticosteroid use, FeNO, SpO2, breath-hold test and questionnaire data [Asthma Control Questionnaire and Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ)]. All measures were collected at Baseline and a three-month follow-up. RESULTS: For the primary outcome, no significant between-group difference was found. Regarding the secondary outcomes, children receiving treatment augmented with BBT revealed significantly greater improvement at the follow-up than those receiving TAU for FEV1_AR (pâ¯=â¯.04, d=-0.50), FEV1_ER (pâ¯=â¯.02, d=-0.52), and the emotional function subscale of the PACQLQ (pâ¯<â¯.01, dâ¯=â¯1.03). No between-group differences were found for the remaining secondary measures of outcome. CONCLUSIONS: Our preliminary findings suggest that the addition of BBT to treatment as usual for children with asthma enhances outcomes with respect to spirometry and parental emotional function but does not lead to reductions in medication, at least over the short term.
