App-Based Yoga of Immortals: A Novel, Easy-to-use Intervention in the Management of Urinary Incontinence.

OBJECTIVE: To study the effectiveness Yoga of Immortals (YOI) intervention in participants with urinary incontinence (UI) of all types. YOI uniquely combines specific yogic postures, breathing exercises, sound therapy & meditation and is practiced by many for general well-being. MATERIALS AND METHODS: In this App-based cohort study, a survey was sent to the YOI app subscribers. Those who identified with UI and consented were sent the ICIQ-UI- SF (for mean symptom score & severity of UI), and the ICIQ-LUTS-QOL (for impact of UI on QOL) Questionnaires at baseline, 4, and 8 weeks. Global impression of improvement was assessed by PGI-I scale. RESULTS: 258/422 participants (18-74 years) were included and showed significant decrease in mean scores on the ICIQ-UI-SF (4.06 ± 0.24 at baseline; 2.90 ± 0.22 at 4-weeks [p ≤ 0.001] and 3.44 ± 0.23 at 8 weeks [p ≤ 0.001]) and ICIQ-LUTS-QOL (28.36± 0.74 at baseline; 24.46± 0.70 at 4-weeks [p ≤ 0.001] and 25.78± 0.70 at 8 weeks [p≤ 0.001]). Additionally, the 55-60 year subgroup also had significant decrease in mean scores on ICIQ-LUTS-QOL (25.06 ±1.20 at base line; 21.69 ± 1.07 at 4 weeks [p ≤ 0.01] and 22.28 ± 0.96 at 8 weeks [p ≤ 0.01]). CONCLUSION: YOI intervention resulted in significant improvement in mean scores on ICIQ-LUTS-QOL; ICIQ-UI-SF; frequency and severity of urinary leak; and daily life activity. Majority of the participants felt 'very much better' on PGI-scale. Being app- based, it has the added advantage of the ability to be used anytime and anywhere.

Black cardamom (Amomum subulatum Roxb.) fruit extracts exhibit apoptotic activity against lung cancer cells.

ETHNOPHARMACOLOGICAL RELEVANCE: The dried fruits of Amomum subulatum Roxb. (A. subulatum) are widely used as a spice. It is a part of official ayurvedic formulations used in folklore medicine to treat cancer.A. subulatum has been used in ayurvedic formulations to treat various lung conditions such as cough, lung congestion, pulmonary tuberculosis. The present traditional knowledge highlights the effectiveness of A. subulatum in treating cancer and its lung-specific efficacy. AIM OF THE STUDY: This study aims to investigate the cytotoxic potential of A. subulatum on the phenomenal and mechanistic level of lung cancer cells and identify the presence of A. subulatum actives. MATERIALS AND METHODS: The bioactivity of the extracts was tested using MTT assay, apoptotic assay, cell cycle analysis, superoxide production assay, reactive oxygen species (ROS) assay, and western blot analysis. Firstly, five different extracts were prepared using sequential extraction, and then screening of cell lines was performed using MTT assay. RESULTS: Lung cancer cells were selected as the most sensitive target, and dichloromethane extract (DE) was the most active extract. Annexin assay confirmed the mode of cell death as apoptosis. SubG1 peak found in cell cycle analysis substantiated this finding. ROS generation and superoxide showed association with apoptotic death. The upregulation and overexpression of cleaved poly(ADP-ribose)polymerase-1 (PARP-1) showed the failure of DNA repairing machinery contributes to apoptosis. LC-MS findings show the presence of cytotoxic actives cardamonin and alpinetin. CONCLUSIONS: In summary, this study shows the apoptosis-inducing potential of A. subulatum fruit extracts and confirms DNA damage as one of the causes of cell death. Further explorations using bio-fractionation and in-vivo studies are required to determine the most active constituents in A. subulatum.

Effectiveness of App-Based Yoga of Immortals (YOI) Intervention for Insomnia in Asian Population during Pandemic Restrictions.

The coronavirus disease 2019 (COVID-19) pandemic created significant psychological challenges worldwide, including stress, emotional distress, and insomnia. In addition, social distancing, travel restrictions, and spread of disease have resulted in unique challenges, creating barriers to healthcare access. Compared to the rate prior to the COVID-19 pandemic, a significant increase in clinical insomnia rates have been reported. With well-known limitations of currently established treatments (e.g., cognitive behavioral therapy-insomnia (CBT-I), pharmacotherapy), there is a need to explore other effective and safe treatment modalities to treat insomnia, especially those that can be used remotely. The purpose of this study is to assess the effectiveness of app-based intervention to treat insomnia in the current era of the COVID-19 pandemic (using the Yoga of Immortals (YOI) app). This prospective cohort study was approved by the Institutional Review Board. All participants in this study were asked to complete an online survey including demographic data and validated Insomnia Severity Index (ISI) at baseline (15 May 2020), 4 weeks, and 8 weeks after starting the YOI intervention. Survey data was exported using Microsoft Excel. Statistical analysis was done using the GraphPad Prism 8. YOI intervention significantly improved the mean ISI scores in all categories of insomnia (severe, moderate, and subthreshold) at each follow-up (p ≤ 0.0001). The improvement was significant among all age groups and in both genders. In our study, YOI was a novel and effective intervention for improving insomnia symptoms and may be a new addition to the armamentarium of insomnia management. Being app-based, this has potential wider applicability, especially during the current COVID-19 pandemic.

Self-assembled lecithin-chitosan nanoparticles improve the oral bioavailability and alter the pharmacokinetics of raloxifene.

In this study, we report the development and evaluation of soy lecithin-chitosan hybrid nanoparticles to improve the oral bioavailability of raloxifene hydrochloride. The nanoparticles were formed by interaction of negatively charged soy lecithin with positively charged chitosan. The ratio of soy lecithin to chitosan was critical for the charge, and hence the size of the nanoparticles. The optimal soy lecithin to chitosan ratio was 20:1 to obtain nanoparticles with particle size of 208 ± 3 nm, a ζ-potential of 36 ± 2 mV and an entrapment efficiency of 73 ± 3%. The nanoparticles were also characterized by differential scanning calorimetry and FT-IR spectrophotometer. In-vitro drug release was assessed using dialysis bag method in pH 7.4 buffer. The drug loaded nanoparticles did not cause significant reduction in the cell viability at low doses. Pharmacokinetic studies in female Wistar rats showed significant improvement (~4.2 folds) in the oral bioavailability of the drug when loaded into nanoparticles. Further, the modified everted gut sac study showed that these nanoparticles are taken up by active endocytic processes in the intestine. The ex-vivo mucoadhesion studies proved that the nanoparticles get bound to the mucus layer of the intestine, which in turn correlates with reduced excretion of the drug in faeces. In conclusion, the proposed nanoparticles appear promising for effective oral delivery of poorly bioavailable drugs like raloxifene hydrochloride.
