Abstract
BACKGROUND Work-related stress negatively impacts employee wellbeing. Stress-management interventions that reduce workplace stress can be challenging. Immersive technologies, such as virtual reality (VR), may provide an alternative. AIMS This systematic review aimed to evaluate feasibility, acceptability, and effectiveness of immersive technologies to promote workplace wellbeing (PROSPERO 268460). METHODS Databases MEDLINE, Web of Science, PsycINFO and Embase were searched until 22nd July 2021. Studies were included if they tested a workforce or were designed for a workplace. Effective Public Health Practice Project quality assessment tool (EPHPP) was used for quality ratings. RESULTS There were 17 studies (N = 1270), published 2011-2021. Over half were conducted in Europe. Eight studies were controlled trials. Most studies involved brief, single sessions of immersive VR and provided evidence of feasibility, acceptability, and effectiveness when measuring wellbeing-related variables such as stress, relaxation, and restoration. VR environments included relaxation tasks such as meditation or breathing exercises, and nature-based stimuli, such as forests, beaches, and water. Studies tested office workers, healthcare professionals, social workers, teachers, and military personnel. EPHPP ratings were "strong" (N = 1), "moderate" (N = 13), and "weak" (N = 3). CONCLUSIONS VR relaxation appears helpful for workplaces. However, limited longer-term data, controlled trials, and naturalistic studies mean conclusions must be drawn cautiously.

Abstract
As the world accelerates, sedentary and unhealthy lifestyles have an increasingly negative impact on human physical and emotional well-being. Millions of people globally are thought to have chronic kidney disease (CKD), which is frequently brought on by diabetes, hypertension, and glomerulonephritis. Over time, the illness gets worse and eventually results in irreversible renal failure. A person's life can be seriously affected by CKD in many different ways, including emotionally, socially, physically, and financially. Apart from physiological manifestations like anemia, discomfort, and exhaustion, CKD can also result in psychological problems like anxiety and depression, which can impair one's overall standard of life. Numerous studies have demonstrated the beneficial effects of yoga and meditation on people with chronic renal disease, enhancing their general health and quality of life. Because of therapeutic limitations, familial pressures, financial restraints, and symptoms of end-stage kidney disease, people with CKD frequently experience stress and anxiety. By reducing stress and anxiety, yoga and meditation can help individuals with chronic conditions maintain their health and improve their overall well-being. Recent research has found that yoga can improve blood pressure, sympathetic activity, and basal metabolic rate as well as reduce blood pressure and blood sugar levels by balancing the autonomic nervous system. Furthermore, studies have demonstrated that yoga helps CKD patients live healthier lives by lowering stress, anxiety, and sadness. Healthcare professionals can help patients with chronic renal disease manage their symptoms and enhance their general health and well-being by adding yoga and meditation into their treatment regimens. Modifying lifestyle is essential for both the prevention and treatment of chronic renal disease. CKD often co-occurs with other age-related and sedentary lifestyles and poor diet-related chronic conditions. The dearth of targeted treatment for a large percentage of CKD patients led to the investigation of the therapeutic applications of yoga and meditation in this study. These affordable, non-invasive therapies provide a comprehensive approach to controlling CKD, benefiting both healthy individuals and those with CKD in terms of their physical and mental well-being.

[PMID: 38463653 PMCID: PMC10919409 DOI: 10.4103/ijoy.ijoy_182_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 03/12/2024] Open
Abstract
The optic nerve comprises approximately 1.2 million axons of retinal ganglion cells and is vulnerable to degeneration due to a myriad of causes. While traditional treatments have been the cornerstone of ocular care, emerging evidence highlights the benefits of integrative approaches, which can be used as an adjunct in the management of optic neuropathy. Yoga is a mind-body energy medicine encompasses physical postures, breath control, and meditation. Currently, it has gained attention for its holistic effects on well-being, by promoting health, preventing onset of diseases, adjunct in disease management, and for its rehabilitative potential. In addition, the underlying mechanisms through which yoga exerts its therapeutic influence, evaluates clinical outcomes, and explores potential synergistic effects with conventional treatments remain largely unexplored. Neuroprotective mechanisms of yoga, such as enhancing retinal ganglion cell function, reducing oxidative stress, coupled with its ability to modulate inflammatory processes and improve circulation, contribute to its potential benefits in visual health. Analysis of clinical studies reveals promising outcomes, including improvements in visual acuity, visual fields, quality of life, and functional outcomes in individuals with optic neuropathy and ocular manifestations who undergo yoga intervention (especially dhyaan) with awareness of breath. Furthermore, the integration of yoga with conventional treatments and complementary modalities unveils the possibilities of multidisciplinary approaches in ocular care that need evaluation. By unraveling the role of yoga intervention in ocular health, this review provides valuable insights for clinicians and researchers, fostering a deeper understanding of the mind-body connection and paving the way for enhanced visual health outcomes. Embracing yoga as an adjunctive therapy may has the potential to revolutionize the management of optic neuropathy and ocular manifestations, offering individuals a holistic approach to optimize visual well-being, reduce comorbid depression and caregiver burden, and improve overall quality of life.

Abstract
Purpose Physical inactivity can be a cause of various lifestyle disorders including atherosclerosis, diabetes, hypertension, and cardiovascular diseases (CVDs). Lifestyle modification by the inclusion of Yoga and similar activities has shown beneficial effects on disease prevention and psychological management. However, the molecular mechanism at the cellular level is unknown. This study aims to identify the molecular response at systemic level generated after three months of Common Yoga Protocol (CYP) practice. Methods A total of 25 healthy adult females were recruited for this study (25 to 55 years). After the drop out of 6 participants at baseline and 2 participants after 1 month; blood samples of 17 participants were assessed. Blood samples were assessed for lipid profile, CD34+ cell enumeration and angiogenesis markers (ie, VEGF, Angiogenin and BDNF) at baseline (before intervention), after one month and after three months of Common Yoga Protocol (CYP) practice. The psychological health of the participants was assessed at baseline and after three months of CYP practice. The psychological tests used were General Health Questionnaire (GHQ), State-Trait Anxiety Inventory (STAI), Trail Making Test A & B, Digit symbol test, Digit symbol substitution test. Results After 3 months of intervention, blood samples of 17 participants were collected and following results were reported (1) percentage of CD34+ cells increased significantly after 3 months of CYP practice (from 18.18±7.32 cells/μL to 42.48±18.83 cells/μL) (effect size: W, 0.40; 95% CI, p = 0.001) (2) neurogenesis marker, ie, BDNF showed a significant change with time after 3 months of CYP intervention (effect size: W, 0.431, 95% CI; p = 0.002), (3) HDL showed an increasing trend (non-significant) after three months of CYP practice (53.017±1.28 mg/dl to 63.94±5.66 mg/dl) (effect size: W, 0.122; 95% CI; p = 0.126) (4) General Health score (10.64 ± 3.53 to 6.52 ± 3.12) (effect size: d, 0.98; 95% CI; p = 0.001) along with visual and executive function improved (69.94±26.21 to 61.88±28.55 (time taken in seconds)) (effect size: d, 0.582; 95% CI; p = 0.036), also stress and anxiety showed reduction (effect size: d, 0.91; 95% CI; p = 0.002) (5) a significant positive correlation was found between: HDL with VEGF (r = 0.547, p = 0.023) and BDNF (r = 0.538, p = 0.039) after 3 months of intervention; also, a significant positive correlation was found between VEGF with BDNF (r = 0.818, p ≤ 0.001) and Angiogenin (r = 0.946, p ≤ 0.001), also, BDNF was also positively correlated with Angiogenin (r = 0.725, p = 0.002) at both 1 month and 3 months after intervention. Also, VEGF and BDNF showed a significantly negative correlation with stress and anxiety questionnaire after the intervention. Conclusion The current study provides insights into the molecular response to CYP practice at systemic level. The results suggest that CYP practice indeed increased CD34+ cells in peripheral blood and BDNF also showed a significant change after the intervention. An overall improvement in general health and psychology of the participants was also observed.

[PMID: 37583537 PMCID: PMC10424270 DOI: 10.4103/ijoy.ijoy_28_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 03/18/2023] [Accepted: 04/05/2023] [Indexed: 08/17/2023] Open
Abstract
Context Intraocular pressure (IOP) increases during "sirasasana" and may be a risk factor for the progression of glaucoma. Other "head below heart" asanas may also cause increase in IOP. Aims To determine the change in IOP following three "head below the heart" postures-"meruasana", "viparithakarni," and "sarvangasana". Settings and Design Prospective observational study conducted in a tertiary care hospital over 3 weeks. Materials and Methods Willing, regular yoga practitioners recruited by purposive sampling performed "meruasana", "viparithakarni," and "sarvangasana" in random order according to a 3 × 3 periods cross over study design after baseline measurement of IOP, blood pressure (BP), and pulse rate. Each asana was held for 30 s. Within 15-30 s of completion of asana, IOP, BP, and pulse rate were recorded. There was an interval of 30 min between the asanas. Statistical Analysis Used Normality of data was tested using the Kolmogorov-Smirnov test. Repeated measures of ANOVA with Tukey-Kramer multiple comparisons was used to compare changes in IOP, BP, pulse rate following asana. P ≤ 0.05 was accepted as statistically significant. Results There were 33 participants with a mean age of 29.6 ± 10.5 years (95% confidence interval [CI]: 26.02, 33.18). The mean baseline IOP was 15.5 ± 3.4 mm Hg (95% CI: 14.34, 16.66) in the right eye and 16.7 ± 3.4 mm Hg (95% CI: 15.54, 17.86) in the left eye. IOP showed a significant reduction following each of the three asanas (P < 0.0001). However, neither pulse rate (P = 0.53) nor BP (P = 0.27) showed any change following the asanas. Conclusions "Meruasana," "viparithakarni," and "sarvangasana" when held for 30 s by healthy yoga practitioners resulted in post-asana drop in IOP with no significant change in pulse rate or BP.

Abstract
OBJECTIVES Yoga is used as a complementary therapy to control the symptomatic and complicated consequences of type 2 diabetes mellitus (T2DM) but the effect of Jyoti-Trataka yoga (gazing steadily at a 4-feet away-fixed candle flame) on the intraocular pressure (IOP), autonomic control, and fasting blood glucose (FBG) in T2DM patients with high-tension primary open-angle glaucoma (POAG) was not previously investigated. This study aimed to search the effect of Jyoti-Trataka on IOP, systolic blood pressure (SBP), respiratory rate (RR), diastolic blood pressure (DBP), FBG, and pulse rate (PR) in T2DM patients with bilateral high-tension POAG. METHODS The patients with a 52- to 67-year range and body mass index below 30 kg/m2 were randomly assigned to one of two 30-patient groups, study or control groups. Besides the administered oral hypoglycemic drugs by both groups, the study group only received one month of daily 55-min Jyoti-Trataka session. RESULTS A significant decrease (p<0.05) was identified after the comparison between the pre and post SBP, RR, DBP, FBG, IOP of both eyes, and PR in the study group while the control group exhibited no significant changes of all measures (p>0.05). In-favor-of the study group, the between-group post-treatment comparison showed a significant improvement of all measures (p<0.05). CONCLUSIONS Jyoti-Trataka is a good yogic complementary therapy that can be used to regulate autonomic functions, blood glucose, and IOP in T2DM patients with high-tension POAG.

Abstract
The coronavirus disease 2019 (COVID-19) outbreak is a public health concern. However, stay-at-home regulations to prevent disease spread increased sedentary behavior with unintended adverse outcomes. Overweight is a major global health issue, and standard treatments have a poor track record of long-term effectiveness. The purpose of this study was to evaluate how online yoga affected participants who were overweight in terms of anthropometric measurements. The study, which was designed as a experimental study, enrolled sixty overweight adolescents. The participants were divided into two groups: a control group (n = 30) and an intervention group (n = 30) who performed an online yoga home exercise program comprising basic yoga practice with 15 poses and minimal rest periods on Monday Wednesday and Friday, from 5.00 to 5.45 pm for 12 weeks. The intensity of the exercise was 65–75 percent of maximum heart rate (MHR). Anthropometric parameters, including body weight (BW), body mass index (BMI), body circumference measurements (BCM), and resting heart rate (RHR) were assessed. All parameters were measured at weeks 0, 8, and 12. Within group and between group comparisons were performed. The results revealed improved BW, BMI, BCM, and RHR in the intervention group; the median BW and BMI of the intervention group was significantly decreased at week 12, and the BCM of the intervention group showed a significant decrease in the chest, waist, hip, and thigh. This declining trend started from week 8. This 12-week online yoga program decreased BW, BMI, BCM, and RHR, which indicates that practicing yoga at home is effective on anthropometric parameters and may be an alternative therapy for health promotion and controlling body weight during the COVID-19 pandemic. However, an appropriate and continuous exercise program must be followed.

Immediate autonomic changes during right nostril breathing and left nostril breathing in regular yoga practitioners. JOURNAL OF EDUCATION AND HEALTH PROMOTION 2022; 11:280. [PMID: 36325230 PMCID: PMC9621351 DOI: 10.4103/jehp.jehp_343_22] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 03/27/2022] [Accepted: 03/30/2022] [Indexed: 05/29/2023]
Abstract
BACKGROUND The ancient Indian science of Yoga makes use of voluntary regulation of breathing to make respiration rhythmic and calm the mind. This practice is called pranayama. Nadisuddhi pranayama means "purification of subtle energy paths," inhalation and exhalation are through alternative nostrils for successive respiratory cycles. Surya Anuloma-Viloma pranayama means "heat generating breathing particle" when the respiratory cycle of inhalation and exhalation is completed through the right nostril exclusively. When completed through the left nostril alone, the practice is called "Chandra Anuloma-Viloma pranayama," which means a heat-dissipating or cooling liberating practice. We compared the effect of right nostril breathing (RNA) and left nostril breathing (LNB) pranayama on heart rate variability. MATERIALS AND METHODS The study was conducted at the Department of Physiology at an institute of national importance, after obtaining necessary ethical approvals from the Institutional Ethics Committee. Twenty healthy kriya yogi volunteers (mean age: 44 years), who are regular practitioners for the last 10-20 years, were inducted into the study. RNB pranayama starts with closing the right nostril with the thumb of the left hand followed by exhalation through the right nostril and inhaling slowly through the same nostril. This forms one round of RNB pranayama. In contrast, inhalation through the left nostril and exhalation through the right nostril exclusively is called chandrabhedana pranayama (chandrabhedana means moon-piercing breath in Sanskrit) with a similar variation called Chandra Anuloma-Viloma pranayama in which inhalation, as well as exhalation, is performed through the left nostril exclusively. The recording of electrocardiogram (ECG) for heart rate variability (HRV) analysis was taken by heart rate variability (Dinamika HRV-Advanced Heart Rate Variability Test System, Moscow, Russia). The resting and during readings of heart rate variability parameters were compared and post hoc analysis was done using Bonferroni and Holm multiple comparisons for repeated measures. RESULTS Time domain parameters: Standard deviation of normal to normal RR intervals (SDNN) and root mean square of successive NN interval differences (RMSSD) were increased at a high level of statistical significance during both pranayama maneuvres. Frequency domain parameters: LF, LF/HF ratio increased significantly. Parasympathetic activity is represented by LF when the respiration rate is lower than 7 breaths per min or during taking a deep breath. Thus, when the subject is in a state of relaxation with slow and even breathing in both RNB-right nostril and Chandra-LNB, the LF values can be very high, indicating an increase in parasympathetic activity rather than an increase in sympathetic regulation. CONCLUSION Our study is an acute study, where changes in HRV were seen after 5 min of RNB and LNB. However, statistically, there is not much difference in the immediate effects of the two pranayamas on heart rate variability in regular yoga practitioners.

The Role of Personalization in the User Experience, Preferences and Engagement with Virtual Reality Environments for Relaxation. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19127237. [PMID: 35742483 PMCID: PMC9223778 DOI: 10.3390/ijerph19127237] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 06/03/2022] [Accepted: 06/08/2022] [Indexed: 12/10/2022]
Abstract
Virtual Reality Environments (VREs) are widely deployed in mental health treatments, often associated with relaxation techniques. The personalization of natural VR-based scenarios is a key element that can further facilitate users’ sense of presence and relaxation. This study explored the role of VREs’ personalization in the user experience with an environment supporting relaxation, by deploying mixed methods. Methods: A non-clinical sample of 20 individuals participated in exposure to a supportive body-scan-guided relaxation VRE. In the personalized conditions, the participants had the option of choosing the context (e.g., sea, mountain, or countryside) and including in the scenario different types of sounds, visual elements, and changing the time of day and weather. In the standard conditions, individuals were exposed to a relaxing VRE, but they could choose neither the context nor the auditory and visual elements. The order of presentation of the personalized vs non-personalized environments was randomized. Measures regarding relaxation, state-anxiety perceived levels, VRE-related symptoms, the usability of the Virtual Reality (VR) setting, sense of presence, pleasure, activation, engagement, and level of immersion experienced were collected before and after exposure to the VR environments. Results: Findings showed that personalized VREs were preferred by users. Participants generally preferred to experience a greater immersivity, pleasure, engagement, and relaxation in the personalized virtual settings. Conclusion: The study further confirms the role of personalization as a component positively contributing to relaxation and engagement. Future research may further assess this effect in the context of large-scale controlled studies involving clinical and non-clinical populations.

Abstract
Aim Common Yoga Protocol (CYP) is a standardized yoga protocol authored by experts from all over the world under the aegis of the Ministry of AYUSH, Ayurveda, Yoga and Naturopathy, Unani, Siddha, Sowa Rigpa and Homeopathy (AYUSH). The potential of CYP can be determined as a cost-effective lifestyle modification to prevent the risk of developing cardiovascular diseases (CVD). Methods In this prospective trial, we compared the effect of CYP at baseline and after 1 month. A total of 374 yoga-naïve participants performed CYP under the supervision of experienced trainers. Physiological [body mass index (BMI), blood pressure, percent oxygen saturation], biochemical (fasting blood glucose and lipid profile), and neurocognitive parameters were measured before and after the intervention. Results At day 30 of yoga practice, serum levels of low-density lipoprotein (LDL), total cholesterol (TC), and high-density lipoprotein (HDL) were found significantly improved as compared to the baseline levels observed at the time of enrollment. Similarly, the lipid profile was also obtained from experienced trainers and found to be significantly different from those of yoga-naïve volunteers. When the intervention was compared between the healthy yoga-naïve participants with yoga-naïve participants suffering from medical issues, it was found that cholesterol profile improved significantly in the healthy-naive group as compared to the diseased group (hypertension, diabetes, underwent surgery, and CVD). Conclusion These results highlight the need for further research to better understand the effects of yoga on the primary prevention of CVD.

Abstract
Yoga is the science of conditioning one's mind and body via the practise of shatkarma, asana, pranayama, mudra, and meditation. The aim of this review of literature is to give theoretical rationale for identifying
(a) the specific attributes of yoga poses that have been used in yoga protocols of various studies but have not been explicitly explored, & (b) the minimum time necessary to keep a posture to bring about a corresponding change in performance among the aforementioned cognitive functions (s) In humans, The most prevalent and under-treated problems are cognitive decline & psychological health problems. Different studies have been carried out to determine the influence of Yoga on human cognitive and psychological health indices. However, no comprehensive examination of the effects of yoga-based therapy on human cognitive and mental health has been undertaken to far. Yoga is an ancient science that places a premium on disease prevention and treatment, as well as the percentage of health. Yoga is recognized to delay the effects of aging and has been found to be effective in the therapy of aging-related disorders. Yoga is a centuries-old discipline that is said to improve both physical and emotional well-being.

Abstract
Background This study aimed to examine the effect of the combination of yoga training with high vitamin D dose supplementation on the expression and systemic levels of inflammatory cytokines and psychophysical status of breast cancer survivors. Methods Thirty volunteered breast cancer survivors (48 ± 8 years) were randomly allocated to a high dose (4000 IU) of vitamin D supplementation (HD) group (n = 10), yoga with a high dose of vitamin D (YHD) group (n = 10), and yoga with a low dose (2000 IU) of vitamin D (YLD) group (n = 10). Participants performed the Hatha yoga style for 12 weeks, twice a week. Blood samples, quality of life (QoL) questionnaire, and physical performance tests were taken before and after the intervention. Results Body fat percentage (ηp2 = 0.36), handgrip strength (ηp2 = 0.41) and QoL indicators include global health (ηp2 = 0.54), functional scales (ηp2 = 0.49), and symptoms scales (ηp2 = 0.50) were significantly improved in the both YHD and YLD groups compared to the HD group (p < 0.05). Also, interleukin-10 (IL-10) levels were markedly increased in the Y-HVD group compared to the Y-LVD and HVD groups. Moreover, there were significant decreases in tumor necrosis factor-α (TNF-α) and interleukin-6 levels in the Y-HVD group after the intervention. The anti-inflammatory index (IL-10/TNF-α) was significantly increased in both the yoga groups (P < 0.05). Conclusion Yoga promotes physical and psychological fitness and, in combination with a high dose of vitamin D, improves the cytokine profile, which can effectively manage the side effects associated with cancer.

Abstract
The COVID-19 pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has negatively impacted the global healthcare and economic systems worldwide. The COVID-19 pandemic has also created an emotional and psychological pandemic among people of all ages irrespective of economic status and physical wellbeing. As a consequence of prolonged lockdowns, one of the most severely affected age groups globally is the young adults' group, especially students. Uncertainties in the academic calendar, restricted outdoor activities, and unusual daily routines during lockdowns led to higher incidences of stress, anxiety, and depression among students worldwide. In this review, we summarise the available evidence on the effect of lockdowns on students and discuss possible positive impacts of yoga and meditation on various psychological, emotional, and immunological parameters, which can significantly influence the general wellbeing and academic performance of students. Perspectives shared in the review will also bring awareness on how yoga and meditation could boost students' performance and assist them in maintaining physical and mental wellbeing during stressful conditions such as future epidemics and pandemics with novel infections. This information could help create better educational curriculums and healthy routines for students.

[PMID: 35444375 PMCID: PMC9015087 DOI: 10.4103/ijoy.ijoy_160_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 01/31/2022] [Accepted: 01/31/2022] [Indexed: 11/29/2022] Open
Abstract
INTRODUCTION In healthy subjects, the intraocular pressure (IOP) is maintained by a dynamic equilibrium between continuous production of aqueous humor by ciliary bodies and continuous outflow through the two drainage pathways: trabecular meshwork and uveoscleral outflow. Here, we hypothesized that yogic ocular exercises, including extraocular muscles exercise, and modified Tratak Kriya (mTK), might reduce the IOP as well as stress and improve quality of life (QoL) in patients with glaucoma. METHODOLOGY A parallel two-arm randomized controlled trial (RCT) was conducted in glaucoma patients (Control group and Intervention group). Control group patients were on standard medical treatment and intervention group patients practiced a Yoga-based lifestyle intervention (YBLI) for 4 weeks as add-on therapy with their standard medical treatment. All Participants were assessed at baseline day 1, day 14 (D14), and day 28 (D28). A minimum of 30 patients were recruited in each group. RESULTS We did not observe any statistically significant different mean IOP of right (IOP-r) or, left eyes at any time point as well as cortisol level and QoL between the two groups. However, with in intervention group, there was a reduction in IOP-r at D14 (15.54 ± 2.81 mmHg) and D28 (15.24 ± 3.1 mmHg), P = 0.006 and 0.001, respectively, compared to their baseline IOP (16.26 ± 2.98). CONCLUSION Based on the present RCT, yoga-based ocular exercises practiced here cannot be recommended for management of raised IOP in glaucoma patients. Further larger studies are warranted with yoga-based interventions in patients with glaucoma. CLINICAL TRIAL REGISTRATION NUMBER CTRI/2016/03/006703.

Abstract
BACKGROUND This study aimed to examine the effect of yoga training combined with vitamin D supplementation on the expression of survival-related genes in leukocytes and psycho-physical status in breast cancer survivors. METHODS Thirty breast cancer survivor women (age, 48 ± 8 yrs) were randomly assigned into three groups: high dose (4000 IU) of vitamin D supplementation (HD) (n = 10); yoga training with a high dose of vitamin D (Y + HD); (n = 10); yoga training with a low dose (2000 IU) of vitamin D (Y + LD) (n = 10). Participants performed the Hatha yoga style twice a week. Blood samples and a battery of psychological and physical tests were taken before and after the completion of interventions. Expression of p53, NF-κB, Bcl2, and Bax genes was measured in leukocytes. RESULTS Body fat percentage (ηp2 = 0.36), shoulder flexibility (ηp2 = 0.38), Rockport walk tests (ηp2 = 0.49), and anxiety (ηp2 = 0.52) were significantly improved in both the Y + HD and Y + LD groups compared to the HD group (p < 0.05). P53 was significantly over-expressed in the Y + HD group while Bcl2 upregulated in both the Y + HD and Y + LD groups. NF-κB and Bax expression downregulated in all groups but were not statistically significant. CONCLUSION yoga training combined with low and high doses of VD improved physical fitness and psychological measures while only in combination with a high dose of VD positively modified the leukocytes cell survival-related gene expression.

Abstract
Objective
We aimed to evaluate and compare the effectiveness of physical and yoga therapies as an adjuvant therapy along with standard pharmacologic treatment in patients with migraine.
Materials and Methods
A total of 61 consenting patients diagnosed to have migraine were randomized into three groups to receive either standard treatment alone, physical therapy along with standard treatment, or yoga therapy along with standard treatment. The respective adjuvant intervention was taught to the respective group of patients and they were advised to perform it daily for 3 months with weekly telephonic reminders and review of their activity logs. Outcome measures assessed were headache frequency, Short-Form McGill Pain Questionnaire (SF-MPQ), and Headache Impact Test-6 (HIT-6) at recruitment and once every month for 3 months.
Statistical Analysis
Statistical analysis of the study was done by using Stata 14.1 software. All the descriptive statistics, paired
t
-test was used to compare the difference between pre and postintervention values of headache frequency, SF-MPQ, and HIT-6 score within all the three groups. Analysis of variance test and post hoc test were used to compare the differences between all groups for outcome measures (
p
< 0.05).
Results
Headache frequency and the visual analog scale before intervention compared during each month intervals for 3 months in all the three groups were significantly decreased in all the three groups (
p
< 0.005). Yoga or physical therapy as an adjuvant to standard treatment leads to a higher reduction in headache frequency and severity. Sensory and affective pain ratings of SF-MPQ and HIT-6 also showed a significant improvement at 1 to 3 months of treatment compared with baseline in all the three groups.
Conclusion
Either physical or yoga therapy as an adjuvant to standard pharmacologic treatment may further improve the quality of life and reduce headache frequency in patients with migraine.

Abstract
PURPOSE Relaxation has significant restorative properties and implications for public health. However, modern, busy lives leave limiting time for relaxation. Virtual reality (VR) experiences of pleasant and calming virtual environments, accessed with a head-mounted display (HMD), appear to promote relaxation. This study aimed to provide a systematic review of feasibility, acceptability, and effectiveness of studies that use VR to promote relaxation in the general population (PROSPERO 195,804). METHODS Web of Science, PsycINFO, Embase, and MEDLINE were searched until 29th June 2020. Studies were included in the review if they used HMD technology to present virtual environments that aimed to promote or measure relaxation, or relaxation-related variables. The Effective Public Health Practice Project (EPHPP) quality assessment tool was used to assess methodological quality of studies. RESULTS 6403 articles were identified through database searching. Nineteen studies published between 2007 and 2020, with 1278 participants, were included in the review. Of these, thirteen were controlled studies. Studies predominantly used natural audio-visual stimuli to promote relaxation. Findings indicate feasibility, acceptability, and short-term effectiveness of VR to increase relaxation and reduce stress. Six studies received an EPHPP rating of 'strong', seven were 'moderate', and six were 'weak'. CONCLUSIONS VR may be a useful tool to promote relaxation in the general population, especially during the COVID-19 pandemic, when stress is increasing worldwide. However, methodological limitations, such as limited randomised controlled trials and longer-term evidence, mean that these conclusions should be drawn with caution. More robust studies are needed to support this promising area of VR relaxation.

Abstract
Context (Background): Type 2 diabetes has been strongly associated with psychosocial factors such as stress, anxiety, depression, and quality of life (QOL). There is not much evidence whether yoga can improve these factors and motivate individuals to engage in active lifestyle. Aims: This study aims to evaluate the effect of yoga and exercise over glycemic control, anxiety, depression, exercise self-efficacy (ESE), and QOL after 3-month program. Methods: Two hundred and twenty-seven individuals were randomly allocated to yoga group (YG) and exercise group. YG practiced yoga for 2 weeks under supervision and then carried out practice at home for 3 months. The exercise group practiced 30 min of brisk walking for 5 days a week. Results: On comparison among the groups, in YG, there was a mean change of 0.47 in glycated hemoglobin which was greater than mean reduction of 0.28 in the exercise group with P < 0.05. State anxiety reduced by 7.8 and trait anxiety reduced by 4.4 in YG (P < 0.05) in 3 months as compared to nonsignificant reductions of 3 and 1 in mean of state and trait anxiety scores in the exercise group (P > 0.05). There was a statistically significant reduction in depression score in both the groups, 8.6 in yoga and 4.0 in exercise, which was greater in YG. ESE improved by 19.2 in YG (P < 0.05), whereas it improved only 2.2 in the exercise group (P > 0.05). QOL improved by 23.7 in YG and 3.0 in the exercise group which was nonsignificant in the exercise group as compared to YG. Conclusions: Yoga is superior to exercise alone as a lifestyle modification program in improving glycemic control, anxiety, depression, and QOL as well as ESE.

Abstract
Background Limited information is available to understand the muscular demands of composite yogasanas such as Surya Namaskar, which is essential to guide prescription of Surya Namaskar in management of commonly prevalent musculoskeletal disorders such as back and knee pain. Aim Therefore, muscle activation pattern in prime accessible muscles of the trunk and lower extremity, namely lower trapezius, latissimus dorsi, erector spinae, rectus abdominis, gluteus maximus, vastus lateralis, and gastrocnemius, was explored during the traditional 12-pose sequence of Surya Namaskar. Methodology Muscle activity of 8 healthy trained yoga practitioners (5 females and 3 males) was recorded using wireless, eight-channel surface electromyography (sEMG) system at a sampling rate of 2000 Hz and bandwidth of 20-450 Hz. Data were processed using EMGworks analysis software, and root mean square values were normalized against muscle activity during maximal voluntary contraction (MVC). Results The 12-pose sequence of Surya Namaskar activated muscles of the trunk, upper and lower extremities to a varying extent, in each pose. During sustenance, erector spinae demonstrated the highest muscle activation in Hastapadasana (64.7% MVC in Pose 3and 64.3% MVC in Pose 11), lower trapezius during Hastapadasana (41.9% MVC in Pose 3and 39.2% in Pose 11); latissimus dorsi during Bhujangasana (37.4% MVC), Ashtangasana (34.9% MVC), and Parvatasana (34.6% MVC in Pose 8,); gluteus maximus in Ashwa Sanchalanasana (38.5% MVC in Poses 9 and 4); and vastus lateralis in Ashwa Sanchalanasana (34.9% MVC). Rectus abdominis demonstrated low activation throughout Surya Namaskar, presenting the highest activation during Parvatasana (22.8% MVC). All recorded muscles demonstrated greater activation during transition compared to sustenance of pose. Conclusion Surya Namaskar elicited high-to-moderate muscle activation of major postural muscles of the trunk and lower extremity during alternating flexion-extension movements of the spine, supporting its prescription in prevention and management of mechanical low back pain among vulnerable groups of people.

Knowledge, Attitude, and Practice of Yoga in Rural and Urban India, KAPY 2017: A Nationwide Cluster Sample Survey. MEDICINES 2020; 7:medicines7020008. [PMID: 32033426 PMCID: PMC7168227 DOI: 10.3390/medicines7020008] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2019] [Revised: 01/11/2020] [Accepted: 01/19/2020] [Indexed: 12/04/2022]
Abstract
Background: To examine the knowledge, attitudes, and practice gap of yoga across India based on implicit perceptions. Methods: The present study is a nationwide door-to-door survey conducted using a questionnaire/screening form. The data were collected from a national survey conducted under the Niyantrit Madhumeh Bharat (NMB) program initiated by The Ministry of Ayurveda, Yoga, Unani, Siddha, Homeopathy (AYUSH), Government of India, from all major zones of the country. A total of 162,330 participants who joined the NMB program were recruited in our study. Results: Out of the total respondents to the survey, it was observed that 11.8% [13,336/112,735] practice yoga, which was highest in the north zone [4,567/112,735] and lowest in the east zone [971/112,735]. Out of 101,643 respondents, 94,135 of the individuals who participated in the survey believed that yoga improved their lifestyle, and 90,102/98,518 believed that yoga prevented diabetes, revealing a huge knowledge–practice gap. Conclusions: The scale of the knowledge–practice gap coupled with the general acceptability of yoga calls for a change in the conventional healthcare provisions by its integration with modern medicine. The population-wide positive perceptions about yoga as a preventive health tool can not only catalyze consensus disease-specific yoga modules but also bridge the knowledge–practice gap that exists because of limited yoga centers and professionals.

Abstract
The world Health Organization defines health as complete well-being in terms of physical, mental and social, and not merely the absence of disease. To attain this, individual should adapt and self-mange the social, physical and emotional challenges of life. Exposure to chronic stress due to urbanization, work stress, nuclear family, pollution, unhealthy food habits, lifestyle, accidental death in the family, and natural calamities are the triggering factors, leading to hormonal imbalance and inflammation in the tissue. The relationship between stress and illness is complex; all chronic illnesses such as cardiovascular disease and asthma have their root in chronic stress attributed by inflammation. In recent times, yoga therapy has emerged as an important complementary alternative medicine for many human diseases. Yoga therapy has a positive impact on mind and body; it acts by incorporating appropriate breathing techniques and mindfulness to attain conscious direction of our awareness of the present moment by meditation, which helps achieve harmony between the body and mind. Studies have also demonstrated the important regulatory effects of yoga therapy on brain structure and functions. Despite these advances, the cellular and molecular mechanisms by which yoga therapy renders its beneficial effects are inadequately known. A growing body of evidence suggests that yoga therapy has immunomodulatory effects. However, the precise mechanistic basis has not been addressed empirically. In this review, we have attempted to highlight the effect of yoga therapy on immune system functioning with an aim to identify important immunological signatures that index the effect of yoga therapy. Toward this, we have summarized the available scientific evidence showing positive impacts of yoga therapy. Finally, we have emphasized the efficacy of yoga in improving physical and mental well-being. Yoga has been a part of Indian culture and tradition for long; now, the time has come to scientifically validate this and implement this as an alternative treatment method for stress-related chronic disease.

Abstract
Metabolic syndrome, a prediabetic and precardiovascular pathologic condition that begins early in life, tracks into adulthood and magnifies with age. Randomized controlled trials evaluating efficacy of yoga-based lifestyle vs. dietary intervention on metabolic syndrome are lacking. Here, the efficacy of a 12-week yoga-based lifestyle intervention vs. dietary intervention on cardio-metabolic risk factors and metabolic syndrome risk scores have been assessed in Indian adults with metabolic syndrome. In this two-arm, open label, parallel group, randomized controlled trial, 260 adults (20-45 years) diagnosed with metabolic syndrome as per joint interim statement, 2009 were randomized to yoga-based (including diet) lifestyle or dietary intervention alone (n = 130, each) for 12 weeks. Primary endpoints were the 12-week changes in cardio-metabolic risk factors and metabolic risk scores. The secondary endpoints were the 12-week changes in the proportion of subjects recovered from metabolic syndrome, dietary intake, and physical activity. Intent-to-treat analysis was performed including all the subjects with baseline data with imputed missing data. Treatment × time interaction showed yoga-based lifestyle intervention had a greater treatment effect over dietary intervention by significantly reducing waist circumference, continuous metabolic syndrome z-score, and dietary intake/day while significantly increasing physical activity. High-density lipoprotein cholesterol showed a significantly greater reduction following dietary intervention than yoga-based lifestyle intervention. A significantly greater proportion of subjects recovered from metabolic syndrome in yoga-based lifestyle (45.4%) vs. dietary intervention group (32.3%). A 12-week yoga-based lifestyle intervention is more efficacious than usual dietary intervention in improving cardio-metabolic risk factor and metabolic risk score in Indian adults with metabolic syndrome.

MEDICINES 2019; 6:medicines6040100. [PMID: 31614579 PMCID: PMC6963794 DOI: 10.3390/medicines6040100] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Revised: 10/06/2019] [Accepted: 10/08/2019] [Indexed: 12/13/2022]
Abstract
Background: Dyslipidemia is considered a risk factor in Type 2 diabetes mellitus (T2DM) resulting in cardio-vascular complications. Yoga practices have shown promising results in alleviating Type 2 Diabetes pathology. Method: In this stratified trial on a Yoga based lifestyle program in cases with Type 2 diabetes, in the rural and urban population from all zones of India, a total of 17,012 adults (>20 years) of both genders were screened for lipid profile and sugar levels. Those who satisfied the selection criteria were taught the Diabetes Yoga Protocol (DYP) for three months and the data were analyzed. Results: Among those with Diabetes, 29.1% had elevated total cholesterol (TC > 200 mg/dL) levels that were higher in urban (69%) than rural (31%) Diabetes patients. There was a positive correlation (p = 0.048) between HbA1c and total cholesterol levels. DYP intervention helped in reducing TC from 232.34 ± 31.48 mg/dL to 189.38 ± 40.23 mg/dL with significant pre post difference (p < 0.001). Conversion rate from high TC (>200 mg/dL) to normal TC (<200 mg/dL) was observed in 60.3% of cases with Type 2 Diabetes Mellitus (T2DM); from high LDL (>130 mg/dL) to normal LDL (<130 mg/dL) in 73.7%; from high triglyceride (>200 mg/dL) to normal triglyceride level (<200 mg/dL) in 63%; from low HDL (<45 mg/dL) to normal HDL (>45 mg/dL) in 43.7% of T2DM patients after three months of DYP. Conclusions: A Yoga lifestyle program designed specifically to manage Diabetes helps in reducing the co-morbidity of dyslipidemia in cases of patients with T2DM.

Abstract
The purpose of this qualitative study was to explore the meaning of acceptance (Thum-jai) as a culturally embedded coping strategy in the lives of Thai people who have experienced adversity that caused suffering. Thematic analysis was used to examine the responses of 47 participants to written, open-ended questions or face-to-face interviews. The EQUATOR's COREQ checklist for qualitative research was followed. Participants came from diverse religious' traditions and geographic regions throughout Thailand. Findings revealed seven themes: circumstance and emotion; thought and action; time, experience, and effort; social and moral support; religious and spiritual ethos; acceptance and hope; and survive and thrive. The adverse circumstance is central to the concept of acceptance. Before acceptance, there is often hope; yet Thai people reach an existential point whether to accept the reality of the situation or continue in distress. Purposeful approaches to deal with the event flow from the cultural contexts of spirituality and social support. Drawing upon psychological strength, Thai people undertake purposive thought and action to facilitate redirecting their lives for better mental health. Thum-jai brings release and peace of mind. Clinicians may find that people experiencing adverse life events are best served by nondirective approaches. Acceptance and change in thoughts and behaviours may come from meditation and therapeutic mindfulness practices that allow those in Western and non-Western cultures to use their own values, expressions, and societal expectations to cope with suffering and formulate effective decisions.

Abstract
Alzheimer's disease (AD) accounts for 80% of all dementia cases, making it the most common form of dementia. Aging serves as the main risk factor for AD, but early onset AD can also occur in individuals younger than 65 years. AD results from progressive neurodegeneration leading to dysfunctional synaptic transmission in the brain. The cascade hypothesis of AD states that amyloid precursor protein (APP) metabolism becomes impaired either by mutation or an interleukin-mediated stress response to injury, resulting in the splicing of harmful oligomeric forms of amyloid beta (Aβ). These oligomers disrupt extracellular receptor binding, intracellular function, and cellular membrane integrity. Yoga and meditative practices slow the progression of the cognitive decline associated with AD. However, the biological mechanisms underlying this therapeutic effect remain elusive. Here, we investigated the ability of neurotransmitters released during yoga and meditative practices to rescue neurons from synaptic dysfunction in an in vitro Alzheimer's model created by culturing basal forebrain cholinergic neurons with physiologically relevant levels of the I-42 isoform of oligomeric Aβ (OΑβI-42). We found that the neurotransmitters dopamine and histamine produce a cooperative action with serotonin to reverse the loss of choline acetyltransferase (CHaT) by OΑβI-42. The loss of ChaT, the enzyme responsible for processing the cholinergic neurotransmitter acetylcholine, contributes to the synaptic dysfunction experienced during AD. These neurotransmitters inhibit nitric oxide synthesis caused by OΑβI-42, preventing oxidative and nitrosative stress. Serotonin activates an alternate cleavage of APP to produce a fragment with known neurotrophic effects, giving it the unique ability to inhibit the OΑβI-42 production cycle. We hypothesize here that these concerted actions lead to the protection of cholinergic synaptic transmission in AD.

Abstract
SUMMARY The term meditation can be used in many different ways, according to the technique to which it refers. Transcendental Meditation (MT) is one of these techniques. TM could serve as a model for research on spiritual meditation, unlike the meditation techniques based on secular knowledge. The purpose of the present study is to conduct a bibliographic review to organize scientific evidence on the effects of TM on neurophysiology, neurochemistry, and cognitive and behavioral aspects of its practitioners. To conduct this critical narrative review of the literature, we searched for scientific papers on the PubMed database of the National Center for Biotechnology Information. The keywords used in the search were Transcendental Meditation, Neuroscience of meditation e Meditation and behavior. We selected 21 papers that analyzed different aspects that could be altered through meditation practice. We concluded that TM has positive and significant documentable neurochemical, neurophysiological, and cognitive-behavioral effects. Among the main effects are the reduction of anxiety and stress (due to the reduction of cortisol and norepinephrine levels), increase of the feeling of pleasure and well-being (due to the increase of the synthesis and release of dopamine and serotonin), and influence on memory recall and possible consolidation. Further studies are needed using creative and innovative methodological designs that analyze different neural circuitry and verify the clinical impact on practitioners.

Abstract
BACKGROUND Yoga is known to contribute towards cardiovascular health. This paper describes the development of a need-based yoga program which is suitable to be integrated into the cardiac rehabilitation of post-myocardial infarction patients with left ventricular dysfunction. MATERIALS AND METHODS Based on the assessment of the need of the patients, literature review, and expert opinion, a yoga module was developed using the qualitative method of inquiry. The program included warm-up exercises, yogic asanas, pranayama, meditation and counseling sessions. A structured questionnaire eliciting comments on the contents was given independently to ten experts working in the field of health and yoga for validation. The final module was derived after incorporating the suggestions of the experts. RESULTS Using the raters' expertise in cardiology and yoga practice, the practices which constitute the module were optimized. Majority of the experts (raters) agreed with the duration of 1 h training for 1month under supervision as adequate for subsequent practice at home. There was a 0.786 inter-rater reliability estimated using the interclass coefficient (ICC) and 0.789 internal consistency of the questions, measured using Cronbach's alpha. Both values indicate "good" reliability and consistency of the yoga module. CONCLUSION The developed yoga module was found to be acceptable. Future randomized control trials will be necessary to validate the effectiveness of this module and if the module demonstrates to be effective by clinical studies, it may add a therapeutic option in the rehabilitation of patients with heart failure following myocardial infarction, which can be applied in the hospitals and community level.

Abstract
OBJECTIVES To assess the feasibility, safety, and initial estimates of efficacy of a yoga program in postoperative care for women at high risk for breast cancer-related lymphedema (BCRL). DESIGN Single-group pretest-post-test design. SETTINGS/LOCATION Patients were recruited from the University of California, San Francisco Carol Franc Buck Breast Care Center. SUBJECTS Twenty-one women were enrolled in the study. Women were >18 years of age, had undergone surgical treatment for breast cancer, and were at high risk for BCRL. INTERVENTION The women participated in an Ashtanga yoga intervention for 8 weeks. Sessions consisted of once/week instructor-led practice and once/week home practice. Particular attention was given to poses that emphasized upper body strength and flexibility, while avoiding significant time with the upper extremity (UE) in a dependent position. OUTCOME MEASURES UE volume was assessed through circumferential forearm measurement, which was converted to volume using the formula for a truncated cone. Range of motion (ROM) was assessed for the shoulders, elbows, and wrists, using a standard goniometer. UE strength was assessed for shoulder abduction, elbow flexion, wrist flexion, and grip using a dynamometer. RESULTS Twenty women completed the yoga intervention, with 17 returning for final assessment. Mean age was 52 (±9.1) years and body mass index was 24.8 (±5.1) kg/m2. Postintervention, mean volume in the at-risk UE was slightly reduced (p = 0.397). ROM for shoulder flexion (p < 0.01) and external rotation (p < 0.05) significantly increased bilaterally. Shoulder abduction ROM significantly improved for the unaffected limb (p = 0.001). Following intervention, strength improved on the affected side for shoulder abduction and grip strength, and bilaterally for elbow flexion (p < 0.05 for all). CONCLUSIONS These preliminary findings suggest that yoga is feasible and safe for women who are at risk for BCRL and may result in small improvements in shoulder ROM and UE strength.

Abstract
A 54-year old married woman was diagnosed with rheumatoid arthritis in 2002, essential hypertension in 2008, type-2 diabetes in 2011 and gangrene over 2nd toe of right foot. She underwent conventional management in private hospitals. Her symptoms, began with moderate to severe pain associated with swelling, stiffness (more in the morning) in multiple joints especially over small joints. In July-2014 she visited our college hospital with the complaints of pain, mild swelling and stiffness over multiple joints associated with poor quality of sleep (QOS) and quality of life (QOL). Subject received integrative Naturopathy and Yoga therapies (INYT) with conventional medicine daily for 10-days. After 10-days, improvements in pain, blood sugar, depression, anxiety, stress, QOS, QOL, blood analysis with normal blood pressure (BP) was observed. This suggests that INYT could be considered as an adjuvant to conventional medicine in RA associated with type-2 diabetes and essential hypertension.

Abstract
Several studies have reported improvements in cognitive communicative abilities with working memory training and alternative therapeutic methods conducted separately. The present study aimed to investigate the effects of combining yoga and working memory training among healthy middle aged adults. A total of 45 participants were randomly assigned into three groups. Group 1 received both yoga and working memory training, group 2 received only working memory training and group 3 served as the control group. Working memory training was provided on six tasks. Yoga training involved pranayamas and mudras. Effects of training were assessed along with the self-perceptual rating of the participants towards training. Results reveal greater training effects among group 1 participants, followed by group 2 and group 3. Group 1 also reported better perception of training (p < 0.05) than group 2. The study highlights that yoga is not only an alternative approach, but also augmentative in improving cognitive communicative abilities.

Abstract
Aim: To study the effect of 6 months yoga program in patients suffering from chronic kidney disease (CKD). Materials and Methods: Fifty-four patients with CKD were studied and divided into two groups (yoga group and control group) to see the effect of yoga in CKD. Patients in the yoga group were offered yoga therapy along with other conventional treatment modalities, while the control group was only on conventional treatment. Subjects in yoga group were trained to perform specific yogic asanas for at least 5 days a week for 40–60 min a day. Regular monitoring of blood pressure, renal function, requirement of a number of dialysis, and quality of life (QOL) indicators were done. Fifty patients (yoga – 25; control-25) completed 6 months follow-up. Results: In yoga group, a significant reduction of systolic and diastolic blood pressure, significant reduction in blood urea and serum creatinine levels, and significant improvement in physical and psychological domain of the World Health Organization QOL (as assessed by BREF QOL scores) were seen after 6 months. In control group, rise of blood pressure, deterioration of renal function, and QOL were observed. Poststudy comparison between the two groups showed a statistically significant reduction of blood pressure, nonsignificant reduction in blood urea and serum creatinine, and significant improvement in physical and psychological domain of QOL in yoga group as compared to control group. For subjects in yoga group, the need for dialysis was less when compared to control group although this difference was statistically insignificant. Except for inability of some patients to perform certain yogic asanas no adverse effect was found in the study. Conclusion: Six months yoga program is safe and effective as an adjuvant therapy in improving renal functions and QOL of CKD patients.

Identification of Altered Metabolomic Profiles Following a Panchakarma-based Ayurvedic Intervention in Healthy Subjects: The Self-Directed Biological Transformation Initiative (SBTI). Sci Rep 2016; 6:32609.

Abstract
The effects of integrative medicine practices such as meditation and Ayurveda on human physiology are not fully understood. The aim of this study was to identify altered metabolomic profiles following an Ayurveda-based intervention. In the experimental group, 65 healthy male and female subjects participated in a 6-day Panchakarma-based Ayurvedic intervention which included herbs, vegetarian diet, meditation, yoga, and massage. A set of 12 plasma phosphatidylcholines decreased (adjusted p < 0.01) post-intervention in the experimental (n = 65) compared to control group (n = 54) after Bonferroni correction for multiple testing; within these compounds, the phosphatidylcholine with the greatest decrease in abundance was PC ae C36:4 (delta = −0.34). Application of a 10% FDR revealed an additional 57 metabolites that were differentially abundant between groups. Pathway analysis suggests that the intervention results in changes in metabolites across many pathways such as phospholipid biosynthesis, choline metabolism, and lipoprotein metabolism. The observed plasma metabolomic alterations may reflect a Panchakarma-induced modulation of metabotypes. Panchakarma promoted statistically significant changes in plasma levels of phosphatidylcholines, sphingomyelins and others in just 6 days. Forthcoming studies that integrate metabolomics with genomic, microbiome and physiological parameters may facilitate a broader systems-level understanding and mechanistic insights into these integrative practices that are employed to promote health and well-being.

Abstract
The human body is machine-like, but self-moving, self-regulating, and self-adjusting, governed by willpower and intelligence. Aging of the body is basically a maintenance problem and so it could perhaps be postponed by thorough and frequent maintenance. Aging brings on a cascade of ills and health problems leading to deterioration of physical, mental, emotional, and social dimensions of life. This paper deals with solution of the problem philosophically in the light of Indian scriptures without entering into traditional bioethical issues. With a meaningful reason for existence, life can be extended. Examining the scientific perspectives on aging, some common manipulations for its extension are discussed. These are calorie restriction, vitamin and antioxidant treatment, exercise and hormonal interventions, etc. Finally, the question of longevity is explored through pursuance of eternal value-based activity and spirituality in the tradition of Indian heritage.

Abstract
The therapeutic potential of meditation for physical and mental well-being is well documented, however the possibility of adverse effects warrants further discussion of the suitability of any particular meditation practice for every given participant. This concern highlights the need for a personalized approach in the meditation practice adjusted for a concrete individual. This can be done by using an objective screening procedure that detects the weak and strong cognitive skills in brain function, thus helping design a tailored meditation training protocol. Quantitative electroencephalogram (qEEG) is a suitable tool that allows identification of individual neurophysiological types. Using qEEG screening can aid developing a meditation training program that maximizes results and minimizes risk of potential negative effects. This brief theoretical-conceptual review provides a discussion of the problem and presents some illustrative results on the usage of qEEG screening for the guidance of mediation personalization.

Abstract
Objective. To investigate the effect of yoga practice on cognitive skills, autonomic nervous system, and heart rate variability by analyzing physiological parameters. Methods. The study was conducted on 30 normal young healthy engineering students. They were randomly selected into two groups: yoga group and control group. The yoga group practiced yoga one and half hour per day for six days in a week, for a period of five months. Results. The yoga practising group showed increased α, β, and δ EEG band powers and significant reduction in θ and γ band powers. The increased α and β power can represent enhanced cognitive functions such as memory and concentration, and that of δ signifies synchronization of brain activity. The heart rate index θ/α decreased, neural activity β/θ increased, attention resource index β/(α + θ) increased, executive load index (δ + θ)/α decreased, and the ratio (δ + θ)/(α + β) decreased. The yoga practice group showed improvement in heart rate variability, increased SDNN/RMSSD, and reduction in LF/HF ratio. Conclusion. Yoga practising group showed significant improvement in various cognitive functions, such as performance enhancement, neural activity, attention, and executive function. It also resulted in increase in the heart rate variability, parasympathetic nervous system activity, and balanced autonomic nervous system reactivity.

Abstract
Recently, infertility treatment-related psychological effects are receiving increased attention. However, whether sexual satisfaction is reduced amongst infertile couples remains to be elucidated. In this study, sexual satisfaction of Japanese infertile couples was assessed using a validated questionnaire designed to assess the male and female partner individually, and the couple as a whole for the first time. This study randomly included 170 infertile couples seen at the outpatient clinic and 170 couples that had recently achieved spontaneous pregnancy. All couples were given the Japanese version of the Golombok-Rust Inventory of Sexual Satisfaction (GRISS). In couples aged 35 years or older, the male partners showed significantly worse sexual satisfaction scores than the female partners. Sexual satisfaction also deteriorated with therapeutic interventions, with mental factors affected more than physical factors. Therapeutic interventions such as timed sexual intercourse and assisted reproductive technology were considered emotionally stressful for infertile couples, with sexual satisfaction accordingly lower in this group than in couples achieving spontaneous pregnancy. GRISS successfully evaluated lower sexual satisfaction associated with infertility, and hence is a useful tool for identifying couples whose sexual satisfaction could be enhanced by counselling or other stress-reduction modalities.

Abstract
Background: Specific nostril breathing is known to influence autonomic functions. Aim: The study was to assess the effects of right nostril breathing (RNB) and left nostril breathing (LNB) on heart rate variability (HRV) and cardiovascular functions. Material and Methods: Eighty-five student volunteers were divided into three groups: RNB group (n = 30), LNB group (n = 30), and control group (n = 25). RNB and LNB group subjects practiced right and left nostril breathing, respectively, every day 1 h for 6 weeks. The control group did not practice nostril breathing. Cardiovascular parameters and spectral indices of HRV were recorded before and after 6-week practice of nostril breathing. In RNB and LNB groups, prediction of rate-pressure product (RPP) by low-frequency to high-frequency ratio (LF-HF) of HRV was assessed by bivariate logistic regression. Results: HRV indices representing sympathetic activity were increased in the RNB group and indices representing parasympathetic activity were increased in LNB group following 6-week nostril breathing. Prediction of LF-HF to RPP, the marker of cardiovascular risks, was more significant (OR 2.65, P = 0.005) in the LNB group compared to the RNB group (OR 1.452, P = 0.016). Conclusions: Short-term practice of LNB improves vagal tone, increases HRV, and promotes cardiovascular health of medical students. Practice of RNB increases sympathetic tone and could jeopardize cardiovascular health.

Abstract
STUDY QUESTION Are women's stress levels prospectively associated with fecundity and infertility? SUMMARY ANSWER Higher levels of stress as measured by salivary alpha-amylase are associated with a longer time-to-pregnancy (TTP) and an increased risk of infertility. WHAT IS KNOWN ALREADY Data suggest that stress and reproduction are interrelated; however, the directionality of that association is unclear. STUDY DESIGN, SIZE, DURATION In 2005-2009, we enrolled 501 couples in a prospective cohort study with preconception enrollment at two research sites (Michigan and Texas, USA). Couples were followed for up to 12 months as they tried to conceive and through pregnancy if it occurred. A total of 401 (80%) couples completed the study protocol and 373 (93%) had complete data available for this analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS Enrolled women collected saliva the morning following enrollment and then the morning following their first observed study menses for the measurement of cortisol and alpha-amylase, which are biomarkers of stress. TTP was measured in cycles. Covariate data were captured on both a baseline questionnaire and daily journals. MAIN RESULTS AND THE ROLE OF CHANCE Among the 401 (80%) women who completed the protocol, 347 (87%) became pregnant and 54 (13%) did not. After adjustment for female age, race, income, and use of alcohol, caffeine and cigarettes while trying to conceive, women in the highest tertile of alpha-amylase exhibited a 29% reduction in fecundity (longer TTP) compared with women in the lowest tertile [fecundability odds ratios (FORs) = 0.71; 95% confidence interval (CI) = (0.51, 1.00); P < 0.05]. This reduction in fecundity translated into a >2-fold increased risk of infertility among these women [relative risk (RR) = 2.07; 95% CI = (1.04, 4.11)]. In contrast, we found no association between salivary cortisol and fecundability. LIMITATIONS, REASONS FOR CAUTION Due to fiscal and logistical concerns, we were unable to collect repeated saliva samples and perceived stress questionnaire data throughout the duration of follow-up. Therefore, we were unable to examine whether stress levels increased as women continued to fail to get pregnant. Our ability to control for potential confounders using time-varying data from the daily journals, however, minimizes residual confounding. WIDER IMPLICATIONS OF THE FINDINGS This is the first US study to demonstrate a prospective association between salivary stress biomarkers and TTP, and the first in the world to observe an association with infertility. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (contracts #N01-HD-3-3355, N01-HD-3-3356, N01-HD-3358).

Abstract
OBJECTIVE Evidence is accumulating, predominantly among clinical trials in adults, that yoga improves blood pressure (BP) control, with downregulation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS) projected as underlying mechanisms. This pilot study assessed whether Hatha yoga has the potential to reduce BP among youth and whether dampening of the SNS and/or HPA activity is a likely pathway of change. DESIGN Thirty-one seventh graders were randomly assigned to a Hatha yoga program (HYP) or attention control (AC) music or art class. Baseline and 3-month evaluations included resting BP; overnight urine samples; and saliva collected at bedtime, upon awakening, and at 30 and 60 minutes after awakening for α-amylase and cortisol assays. RESULTS Twenty-eight (14 in the HYP group and 14 in the AC group) students were assessed both before and after the intervention. BP changes from pre- to post-intervention were -3.0/-2.0 mmHg for the HYP group and -0.07/-0.79 mmHg for the AC group (p=0.30 and 0.57, respectively). Changes in systolic BP (SBP)/diastolic BP (DBP) for the prehypertensive (75th-94th percentiles for SBP) subgroup analyses were -10.75/-8.25 mmHg for the HYP group (n=4) versus 1.8/1.0 mmHg for the AC group (n=5) (p for SBP=0.02; p for DBP=0.09). Although no statistically significant group differences were observed with changes in SNS or HPA awakening curves (area under curve for α-amylase and cortisol, respectively), a small to moderate effect size was seen favoring a reduction of α-amylase activation for the HYP group (Cohen d=0.34; prehypertensive d=0.20). CONCLUSIONS A school-based Hatha yoga program demonstrated potential to decrease resting BP, particularly among prehypertensive youth. Reduced SNS drive may be an underlying neurohormonal pathway beneficially affected by the program. A large-scale efficacy/effectiveness randomized clinical trial is warranted.

Abstract
AIM This randomized controlled trial was carried out to investigate the effect of mindfulness eating and yoga exercise on blood sugar levels among pregnant Thai women with GDM. BACKGROUND Interventions promoting achievement of good glycemic control result in desired pregnancy outcomes. Little is known about the health benefits of mindfulness eating and yoga exercise on blood sugar levels among pregnant with GDM. METHODS A randomized controlled trial was carried out. Main outcome measures were capillary fasting plasma glucose, 2-h postprandial blood glucose, and hemoglobin A1c. RESULTS The intervention group showed significantly reduced fasting plasma glucose, 2-h postprandial blood glucose, and glycosylated hemoglobin (HbA1c) in the intervention group (p<0.05). CONCLUSIONS Mindfulness eating and yoga exercise had health benefits on glycemic control in pregnant women with GDM. It should be recommended in clinical and community health services.

Abstract
Sustained attention (SA) is a vital function mediated by the right frontal - parietal cortex. The digit vigilance test (DVT) measures SA. Assessment of SA in students for their academic excellence is considered to be an essential part of a neuropsychological evaluation. The objective of this study is to determine SA in students undergoing training of integrated Yoga module (IYM). A total of 66 university students aged between 18-37 years participated in this study with a single group pre-post design. The DVT data was collected before and after the IYM. Statistical Package for Social Sciences version 19 was used for data analysis. The Kolmogorov-Smirnov test showed that the data were not normally distributed. The Wilcoxon's signed ranks test was used to compare means of data. The data analysis showed 11.66% decrease (P < 0.001) in total time taken for DVT and 31.90% decrease (P < 0.001) in error scores for DVT. The present study suggests that IYM can result in improvement of SA among students, thus paving the way for their academic excellence. Additional well-designed studies are needed before a strong recommendation can be made.

Abstract
Effect of different meditation practices on various aspects of mental and physical health is receiving growing attention. The present paper reviews evidence on the effects of several mediation practices on cognitive functions in the context of aging and neurodegenerative diseases. The effect of meditation in this area is still poorly explored. Seven studies were detected through the databases search, which explores the effect of meditation on attention, memory, executive functions, and other miscellaneous measures of cognition in a sample of older people and people suffering from neurodegenerative diseases. Overall, reviewed studies suggested a positive effect of meditation techniques, particularly in the area of attention, as well as memory, verbal fluency, and cognitive flexibility. These findings are discussed in the context of MRI studies suggesting structural correlates of the effects. Meditation can be a potentially suitable non-pharmacological intervention aimed at the prevention of cognitive decline in the elderly. However, the conclusions of these studies are limited by their methodological flaws and differences of various types of meditation techniques. Further research in this direction could help to verify the validity of the findings and clarify the problematic aspects.
