Self reported benefits of participating in group prayer in a hospital outpatient setting: A cross-sectional observational study.

BACKGROUND: Prayer had long been used as a tool to bring hope among patients suffering with intractable diseases. Most clinical researches conducted so far on prayer were done upon indoor patients. Effects of prayer involving patients and health care providers in a hospital outpatient setting have never been explored. OBJECTIVES: This cross sectional study aimed to observe the self-perceived changes post prayer among patients and hospital staff involved in the health care delivery and who actually have participated in the prayer sessions. MATERIAL AND METHOD: Survey was conducted with the help of a structured questionnaire on routine OP days at Ayurveda -Arthritis Treatment and Advanced Research Center, Lucknow. Patients visiting the center for OP based consultation and hospital staff who has participated in any prayer session were eligible to participate in the survey. RESULTS: 49 hospital staff and 85 patients have participated in the survey. Among most important self-reported attributes following the prayer sessions in patients were Positive Attitude (84.70%), Optimism about cure (92.90%), Feeling of well-being (95.30%), Optimism about future (95.30%) and Changes in energy level (89.40%). Among hospital staff the important attributes were related to change in energy level (93.90%), increased empathy (93.90%), feeling of universal good (96.00%), less fatigue post prayer (69.40%), sustained effects (81.60%) and healthier feeling (81.60%). CONCLUSION: This observational study suggests that a simple prayer session in outpatient department may be helpful in inculcating hope and building self-esteem among patients and can bring a better self-image, efficiency and connectedness in the hospital staff. Eventually, this may help in improving the outcomes and quality of care being provided at outpatient setting at any hospital.

Multimodal fluorescence imaging and spectroscopic techniques for oral cancer screening: a real-time approach.

The survival rate of oral squamous cell carcinoma (OSCC) patients is very poor, but it can be improved using highly sensitive, specific, and accurate techniques. Autofluorescence and fluorescence techniques are very sensitive and helpful in cancer screening; being directly linked with the molecular levels of human tissue, they can be used as a quantitative tool for cancer detection. Here, we report the development of multi-modal autofluorescence and fluorescence imaging and spectroscopic (MAF-IS) smartphone-based systems for fast and real-time oral cancer screening. MAF-IS system is indigenously developed and offers the advantages of being a low-cost, handy, non-contact, non-invasive, and easily operable device that can be employed in hospitals, including low-resource settings. In this study, we report the results of 43 individuals with 28 OSCC and 15 oral potentially malignant disorders (OPMDs), i.e., epithelial dysplasia and oral submucous fibrosis, using the developed devices. We observed a red shift in fluorescence emission spectrain vivo. We found red-shift of 7.72 ± 6 nm, 3 ± 4.36 nm, and 1.33 ± 0.47 nm in the case of OSCC, epithelial dysplasia, and oral submucous fibrosis, respectively, compared to normal. The results were compared with histopathology and found to be consistent. Further, the MAF-IS system provides results in real-time with higher accuracy and sensitivity compared to devices using a single modality. Our system can achieve an accuracy of 97% with sensitivity and specificity of 100% and 94.7%, respectively, even with a smaller number of patients (28 patients of OSCC). The proposed MAF-IS device has great potential for fast screening and diagnosis of oral cancer in the future.

Development of multimodal micro-endoscopic system with oblique illumination for simultaneous fluorescence imaging and spectroscopy of oral cancer.

Multimodality of an optical system implies the use of one or more optical techniques to improve the system's overall performance and maximum utility. In this article, we demonstrate a multimodal system with oblique illumination that combines two different techniques; fluorescence micro-endoscopy and spectroscopy simultaneously and can be utilized to obtain diverse information from the same location of biological sample. In present system, use of graded index (GRIN) rod-lens makes it highly compact and oblique incidence decouples illumination geometry with collection geometry, preventing CCD cameras from saturation and reduces number of optical elements, thereby making system further miniaturized and field-portable. It also overcomes the disadvantages of undesired reflections from different optical elements. The experimental results of simultaneous imaging and spectroscopy of the biological samples are presented along with quantitative spectroscopic parameters; peak wavelength shift, area under the curve and full width half maximum (FWHM). The spatial resolution, spectral resolution and field of view of the system are found to be 4.38 µm, 0.5 nm and 2.071×1.548mm2 , respectively. Furthermore, we have obtained the red shift for cancerous oral tissue with respect to normal oral tissue 5.79 ± 1.071 nm. This could be important indicator for oral cancer screening.
