OBJECTIVE: Cancer patients undergoing chemotherapy continue to experience significant fatigue, which affects their quality of life. The present study aims to evaluate the combined effect of comprehensive physical exercise, pranayama (regulated breathing practices of yoga), and dietary support intervention on fatigue in cancer patients undergoing chemotherapy.
METHODS: Non-advanced adult cancer patients undergoing chemotherapy (N = 52) were randomized into the intervention group (N = 26) or control group (N = 26). Fatigue assessment was done using the Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue Scale (version 4) at baseline and after 3 months. The intervention group participants practiced physical exercise, slow-paced pranayama and supplemented their diet with an intake of 100 g of millet protein powder (MPP), commonly known as \"Sattu\" in India. The control group received standard medical care.
RESULTS: A total of 39 patients (N = 13 in the intervention and N = 26 in the control group) were included in the statistical analysis. Within the intervention group, a statistically significant reduction in fatigue (p = 0.002) with a large effect size (d = 2.1) was observed. There was no statistically significant reduction in fatigue within the control group (p = 0.36). The group comparison showed a statistically significant reduction in post-scores of fatigue (p < 0.0001) in the intervention group as compared to the control group with a moderate effect size (R = 0.1). No unintended adverse effects related to the intervention were observed.
CONCLUSIONS: The results suggest the potential role of integrated physical exercise, pranayama, and dietary support in reducing fatigue in cancer patients undergoing chemotherapy. Further validation with a larger sample size is required.
BACKGROUND: CTRI/2022/04/041717 [Registered prospectively on 07/04/2022].

BACKGROUND: Hypertension, a significant risk factor for cardiovascular disease, has a high prevalence rate globally. While drug use is the most common approach, lifestyle improvements are crucial. Recently, there has been a notable upsurge of interest in various breathing methods, including device-induced breathing techniques like Resperate. However, the reliance on a device for these techniques has prompted the popularity of alternative breathing methods that can be performed without any external devices. One such method that has gained significant attention is alternative nostril breathing, which serves as an alternative medical treatment known for its effectiveness in reducing blood pressure. Therefore, this study aimed to systematically investigate the therapeutic effects of alternate nostril breathing.
METHODS: We selected 16 articles published in English, Korean, and Chinese databases, of which 14 met the eligibility criteria, and a systematic literature review was conducted. A meta-analysis was conducted on six qualified studies. Meta and sensitivity analyses were conducted using a random effects model of six randomized clinical trials (RCTs).
RESULTS: Results of alternative nostril breathing (ANB) on 1,377 participants have been reported based on the effects of systolic and diastolic blood pressure (SBP and DBP). Both the lone ANB and combined yoga programs resulted in significant reductions in SBP and DBP. Meta-analysis of the 6 trials with 525 participants demonstrated that ANB was better in reducing SBP than that of the control group (nonintervention or placebo) (mean difference [MD]: -7.16, 95% confidence interval [CI]: -7.86 to -6.45, I2: 93%). Moreover, ANB was better in reducing DBP than that of the control group (nonintervention or placebo) (MD: -5.16, 95% CI: -5.89 to -4.44, I2: 87%).
CONCLUSIONS: The results of the study are valid; however, attention is needed when interpreting the results because the heterogeneity exceeds 75%. A systematic review of 14 studies found that ANB can improve cardiovascular indicators, such as SBP and DBP, as well as non-cardiovascular factors, such as fatigue, intraocular pressure, and memory. However, the review noted that implementing double blinding in studies on yoga breathing intervention is difficult, and most studies were not double-blinded, suggesting the need for high-quality RCTs in the future.
Hypertonie, ein signifikanter Risikofaktor für kardiovaskuläre Erkrankungen, hat weltweit eine hohe Prävalenz. Der gängigste Behandlungsansatz ist der medikamentöse, doch auch Maßnahmen der Lebensführung sind entscheidend. Aktuell ist ein sprunghafter Anstieg des Interesses an verschiedenen Atemmethoden zu verzeichnen, einschließlich gerätegestützter Atemtechniken wie Resperate. Doch das Angewiesensein auf ein Gerät, das mit diesen Techniken einhergeht, hat alternative Atemmethoden an Beliebtheit gewinnen lassen, für die man keine externen Geräte braucht. Eine solche Methode, die viel Aufmerksamkeit erfahren hat, ist die Wechselatmung. Die therapeutischen Effekte dieser wechselseitigen Nasenloch-Atmung sind daher der Gegenstand der vorliegenden systematischen Untersuchung. Wir wählten aus englischen, koreanischen und chinesischen Datenbanken 16 Artikel aus, von denen 14 die Einschlusskriterien erfüllten, und führten eine systematische Literaturauswertung durch. Eine Metaanalyse wurde an sechs qualifizierten Studien durchgeführt. Die Meta- und Sensitivitätsanalysen wurden an sechs randomisierten klinischen Studien (RCT) mit einem Zufällige-Effekte-Modell durchgeführt. Die Resultate der Wechselatmung (WA) bei den 1’377 Studienteilnehmern wurden anhand der Effekte auf den systolischen und diastolischen Blutdruck (SBD und DBD) berichtet. Die WA führte sowohl allein als auch im Rahmen eines Yogaprogramms zu signifikanten Reduktionen des SBD und DBD. Metaanalysen der 6 Studien mit insgesamt 525 Teilnehmern ergaben, dann die WA der jeweiligen Kontrollgruppe (keine Intervention oder Placebo) im Hinblick auf die SBD-Reduktion überlegen war (mittlere Differenz [MD]: −7,16; 95%-Konfidenzintervall [KI]: −7,86 bis −6,45; I2: 93%). Darüber hinaus war die WA der Kontrollgruppe (keine Intervention oder Placebo) auch im Hinblick auf die DBD-Reduktion überlegen (MD: −5,16; 95%-KI: −5,89 bis −4,44; I2: 87%). Die Ergebnisse der Studie sind valide, jedoch sind sie mit Vorsicht zu interpretieren, da die Heterogenität 75% überschreitet. Eine systematische Übersicht von 14 Studien ergab, dass die WA kardiovaskuläre Indikatoren wie den SBD und DBD sowie nicht-kardiovaskuläre Faktoren wie Ermüdung, Augeninnendruck und Erinnerungsvermögen günstig beeinflussen kann. Die Übersicht ergab jedoch auch, dass es schwierig ist, in Studien zu Yoga-Atmung eine doppelte Verblindung umzusetzen, und dass die meisten Studien nicht doppelt verblindet waren, was den Bedarf an RCT hoher Qualität in der Zukunft unterstreicht.

OBJECTIVE: To compare the effects of Yoga with traditional exercise on the mobility and functional capacity of individuals with ankylosing spondylitis (AS).
METHODS: The participants of the study were recruited at the rheumatology department, adhering to the study\'s inclusion and exclusion criteria. Participants were randomized into two groups (Group A - Yoga, and Group B - exercise).The candidates participated in an 8-week intervention consisting of 3 weekly sessions of either Yoga or Exercise intervention. Outcomes were collected at pre-treatment, at 8 weeks, and at 12 weeks.
RESULTS: The within-group comparison showed an improvement in all outcome measures with p < .05 between post-treatment and the follow-up. In the yoga group, there was an improvement in the measures of BASMI (p = .001), BASFI (p = .005), PSQI (p = .021), CE (p = .053) and NPRS (p = .001). Similarly, in the exercise group, there was an improvement in BASMI (p = .002), BASFI (p = .003), PSQI (p = .010), CE (p = .004) and NPRS (p = .001). In the between group comparison at post-treatment, there were no statistically significant differences in BASMI (yoga = 3.0 ± 1.50, exercise = 2.3 ± 1.38), PSQI (yoga = 5.3 ± 1.50, exercise = 4.9 ± 1.17) and NPRS (yoga = 1.3 ± 2.22, exercise = 0.4 ± 0.50) CE (yoga = 4.0 ± 1.18, exercise = 3.4 ± 0.96), BASFI (yoga = 1.8 ± 2.14, exercise = 2.1 ± 1.87).
CONCLUSIONS: The results demonstrated a statistically significant improvement in within-group scores of mobility, functional capacity, sleep quality and pain in AS patients of both intervention programs but there were no significant differences between the groups.

Healthcare professionals (HCPs) had to perform their duties under extremely trying circumstances during the COVID-19 pandemic. High expectations further increased HCP\'s stress, which had an adverse impact on their mental health. The present quasi-randomised clinical trial examined how a specially designed pranayama regimen practised for 4 weeks affected the mental health of frontline, exposed HCPs in terms of perceived stress, wellness and quality of life. A total of 280 frontline HCPs on COVID-19 duties in five public hospitals of Delhi, India participated in this study. The intervention (n = 123) and control (n = 127) groups were alternately allocated. Data on perceived, self-reported mental health of HCPs were collected at baseline and post-test at the end-line (after 28 days of practice). We report that the intervention group (n = 123) had a substantial lower perceived stress at post-test at the end-line in comparison to the control group (n = 127, p-value: .028). Their overall WHO Quality-of-Life score also improved, of which the score on psychological domain increased significantly (p-value: .019). Accordingly, we conclude that a 28-day practice of the pranayama by the frontline HCPs in COVID-19 hospitals significantly decreased their level of perceived stress and enhanced their psychological quality of life.

Elevated blood pressure is one of the major risk factors for cardiovascular diseases. Available evidence on mind-body medicine (MBM) techniques on blood pressure is inconclusive and provides conflicting results. The objective of the current systematic review and meta-analysis is to evaluate the effect of MBM techniques on blood pressure in patients with cardiovascular disease. Randomized control trials (RCTs) done between the years 2000 and 2020 on cardiovascular disease, using MBM techniques such as meditation, mindfulness-based stress reduction and relaxation techniques were searched through electronic databases such as PubMed, Cumulative Index to Nursing & Allied Health (CINAHL), EMBASE and Cochrane Library. Three authors independently performed article selection, data extraction and validation. Meta-analysis was performed using a random effect model and standardized mean difference (SMD) with 95% confidence interval (CI) estimated for the effect size. Fifteen RCTs with 927 patients were included in the meta-analysis. Heterogeneity among the studies was very high for all analyses (I2>94%). For studies comparing systolic blood pressure, MBM interventions show a significant (p=0.01) effect when compared to conventional treatment, an overall estimated effect size of SMD - 0.78 (95% CI: -1.36, -0.20). For studies comparing the diastolic blood pressure, MBM intervention did not show any significant effect when compared to the conventional treatment, an overall effect size of SMD -0.26 (95% CI: -0.91, 0.39). The findings of the meta-analysis suggest that MBM interventions may improve systolic blood pressure alone in patients with cardiac diseases. With high heterogeneity and low quality of the included studies, more robust evidence is required before suggesting MBM as an effective treatment modality for reducing blood pressure in cardiovascular diseases.

The impact of controlled breathing on cognitive and affective processing has been recognized since ancient times, giving rise to multiple practices aimed at achieving different psychophysical states, mostly related to mental clarity and focus, stress reduction, and relaxation. Previous scientific research explored the effects of forced unilateral nostril breathing (UNB) on brain activity and emotional and cognitive functions. Some evidence concluded that it had a contralateral effect, while other studies presented controversial results, making it difficult to come to an unambiguous interpretation. Also, a few studies specifically addressed wellbeing. In the present study, we invited a pilot sample of 20 participants to take part in an 8-day training program for breathing, and each person was assigned to either a unilateral right nostril (URNB) or left nostril breathing condition (ULNB). Then, each day, we assessed the participants\' wellbeing indices using their moods and mind wandering scales. The results revealed that, after the daily practice, both groups reported improved wellbeing perception. However, the effect was specifically related to the nostril involved. URNB produced more benefits in terms of stress reduction and relaxation, while ULNB significantly and increasingly reduced mind-wandering occurrences over time. Our results suggest that UNB can be effectively used to increase wellbeing in the general population. Additionally, they support the idea that understanding the effects of unilateral breathing on wellbeing and cognition requires a complex interpretive model with multiple brain networks to address bottom-up and top-down processes.

UNASSIGNED: Yogic breathing helps in reduction of stress and strain in the body. Right and left nostril breathings (RNB and LNB, respectively) have different effects on cardiorespiratory parameters. The study was performed to examine the effect of RNB exercise on cardiorespiratory parameters and reaction time in young, healthy human volunteers.
UNASSIGNED: In this prospective, interventional study, 110 young healthy volunteers underwent systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate (PR), respiratory rate (RR), vital capacity (VC), peak expiratory flow rate (PEFR), and reaction time (RT) examination before and after 2 weeks of performing 45 min of RNB exercise daily.
UNASSIGNED: There was notable increment in SBP (113.39 ± 17.72 vs. 117.74 ± 10.83 mmHg, P = 0.002) and DBP (67.64 ± 10.32 vs. 71.27 ± 8.68 mmHg, P = 0.002). PR increased nonsignificantly (86.44 ± 12.65/min vs. 87.32 ± 13.43/min, P = 0.476). Significant decrease in RR (14.40 ± 2.48/min vs. 12.31 ± 2.23/min, P < 0.0001) was observed. VC (3.57 ± 0.57 vs. 3.82 ± 0.55 L/min, P < 0.0001) and PEFR (441.36 ± 50.22 vs. 468.91 ± 53.66 L/min, P < 0.0001) also increased significantly. Substantial reduction in auditory reaction time (ART) (165.58 ± 32.18 vs. 147.42 ± 23.39 ms, P < 0.0001) and visual reaction time (VRT) (191.04 ± 37.94 vs. 165.86 ± 28.74 ms, P < 0.0001) was seen. After engaging in cardiorespiratory exercise, the maximal heart rate (MHR) remained unchanged (P = 0.929).
UNASSIGNED: RNB results in increase in blood pressure, heart rate, VC, and PEFR and decrease in ART and VRT. Further studies in patients with cardiorespiratory diseases are necessary to understand its clinical utility.

Systemic hypertension is an established risk factor for coronary artery disease and cerebrovascular accident and control of blood pressure reduces the risk of a major cardiovascular event. Both non-pharmacological and pharmacological treatment options are available to treat hypertension. Yoga, recently received more attention as a treatment modality for various lifestyle disorders, even though practiced in India since ancient times. In this review, we are analyzing the role of yoga in the treatment of systemic hypertension.

Introduction: During the COVID-19 pandemic, health care workers (HCWs) experienced increased anxiety, depression, loneliness, and other mental health issues. HCWs need additional resources to cope with the mental health impact of their work. Yoga techniques could be helpful strategies to manage different stressors during times of uncertainty. Methods: This prospective, single-arm, trial examined the effects of a brief pranayama yoga practice on the wellbeing of HCWs during the height of COVID-19. HCWs were recruited through announcements and institutional websites at a large major cancer center in the southern United States. A short, prerecorded, 5-min breathwork video intervention called \"Simha Kriya\" was provided to participants, and they were encouraged to practice one to two times daily for 4 weeks. Participants completed self-report instruments at baseline and weeks 1 and 4, including: (1) Perceived Stress Scale (PSS); (2) Brief Resilient Coping Scale (BRCS); and (3) a questionnaire assessing the experience of COVID-19 among HCWs that had five subscales. HCWs also conducted a measure of breath holding time. Paired sample t-tests and mixed-effects analysis of variance models examined changes over time. Results: One hundred participants consented to the study, with 88 female, 60 white, 39 worked remotely, and 27 were clinical staff. Sixty-nine participants provided data at week 1 and 56 at week 4. Participants\' adherence to the breathing exercises between weeks 1 and 4 was similar, with a mean of six times per week. At week 4, there were significant decreases in the COVID-19 Distress score (p < 0.0001) and COVID-19 Disruption (p = 0.013), yet no changes in the PSS. There were also significant increases in COVID-19 Stress Management (p = 0.0001) and BRCS scores (p = 0.012), but no changes in Perceived Benefits of COVID-19 and no changes in breath holding time. Discussion: Brief yoga-based breathing practices helped reduce pandemic-specific stress, improved resilience, and stress management skills in HCWs. Trial Registration Number: NCT04482647.

Pranayama, a set of yogic breathing techniques, is being studied as a potential supportive care option for cancer patients. This review intends to evaluate the effectiveness of Pranayama in enhancing the quality of life and well-being of cancer patients based on evidence from randomized controlled trials. We thoroughly searched databases for studies published between 2013 and 2023. We focused on randomized controlled trials that compared Pranayama interventions with non-yoga control groups. We assessed the primary outcomes, including psychological well-being, quality of life, physiological parameters, and treatment-related side effects. The review indicates that practicing Pranayama can lead to significant improvements in antioxidant levels, stress, anxiety, sleep quality, and overall quality of life for cancer patients. However, the evidence comes from a limited number of studies, which vary in sample sizes and methodologies. Pranayama shows promise as a complementary therapy for cancer patients, potentially enhancing their well-being and quality of life. Nonetheless, the current evidence base is limited, necessitating further research with larger sample sizes and more rigorous study designs to confirm these findings and elucidate the underlying mechanisms.
