How Is It Possible to Treat Diseases Without Medicine?: A Qualitative Study on the Attitude and Perceived Benefits of Yoga and Naturopathy Among Patients Admitted at an Inpatient Hospital.

Background: Yoga and naturopathy (Y&N) is a system of medicine primarily focusing on restoration of health and well-being. Objective of this study is to understand the knowledge, attitude, and perception about Y&N among the inpatients of a government Y&N institution in south India. Methods: Focus group discussion was conducted in eight adult patients aged between 30 and 60 years who took Y&N treatments for a period of 10 days or more. Purposive sampling method was adopted. Oral informed consent was obtained. Results: Knowledge about the Y&N system of medicine was primarily through referral or "word of mouth." Perceived benefits were both physical and psychological. Uniqueness of the hospital as mentioned by participants includes individual attention, tailor-made treatment protocols, and one-to-one care to the needy patients. Conclusion: An integrated approach is very much essential that might bring about better treatment outcomes in patients.

Bite force evaluation at maximal intercuspal position: An in vivo comparative study between stainless steel and zirconia crowns on primary molar teeth.

Objective: The objective of this study was to clinically evaluate and compare the mean bite force changes at maximum intercuspal position, along with parental satisfaction following full crown restoration using stainless steel crown/zirconia crown on primary molar teeth using digital occlusal analysis system T-Scan III (Tekscan Corp, Boston, Mass., USA). Materials and Methods: Thirty-six primary molars of children aged 6-9 years with pulpal involvement were selected for the study. The selected teeth were allocated to either of the two groups using simple random sampling technique: Group A = stainless steel crowned teeth and Group B = zirconia crowned teeth. The mean bite force was recorded before the placement of the crown, after the placement of the crown, and after 1 month-follow-up. The inter-group and intra-group comparison was done among the groups. After the placement of the crown, parents were asked to fill out a questionnaire for assessing parental satisfaction. Results: A significant result in the bite force on crowned tooth, vertical dimension was seen from baseline to 1-month follow-up between the SSC and zirconia groups. In the zirconia crown group, the mean bite force was more compared to the stainless steel crown group. Parents' satisfaction was higher with zirconia crown in terms of color and esthetics. Conclusion: SSC is more acceptable than zirconia crown since occlusal re-equilibration was attained better in SSC as compared to zirconia crown.

Effects of Therapeutic Calf Massage on Cardiac Autonomic Function in Healthy Volunteers-a Pilot Study.

Background: Calf massage is a therapeutic intervention that improves circulation and relieves us from pain & tightness. The calf massage also improves autonomic performance by modulating the vagal tone of the cardiovascular system. Therefore, the current study was intended to determine therapeutic calf massage on cardio autonomic activity in healthy subjects. Objective: To assess the immediate effect of a single 20-min session of calf massage on cardiac autonomic modulation through heart rate variability (HRV) measurement. Materials & Methods: In this study, 26 apparent healthy female participants aged between 18 and 25 years participated. Massage over the calf muscles on both legs for 20 min was performed, and resting cardiovascular parameters and HRV parameters were measured at baseline, immediately after the massage, and during the recovery periods (10 and 30 min after the massage). Data were analyzed using one-way ANOVA followed with post hoc analysis. Results: Immediately after the massage intervention, heart rate (HR), systolic (SBP), and diastolic (DBP) blood pressure were decreased (p < .01), and the reduction was persisted at 10 min and 30 min of the recovery period (p < .01). In HRV parameters, the root mean square of successive differences (RMSSD) and high-frequency normalized unit (HF n.u.) increased, and low frequency (LF n.u.) decreased after the massage, and at the 10 and 30 min of the recovery period. Conclusion: The present study reports suggest a significant reduction in heart rate and blood pressure after the massage therapy. A drop in sympathetic tone and raise in parasympathetic tone can also attribute to the therapeutic effect.

Foot reflexology for reduction of blood pressure in hypertensive individual: A systematic review.

IMPORTANCE: Hypertension is the modifiable risk factor associated with cardiovascular diseases and all-cause mortality. Foot reflexology has been proposed to reduce the blood pressure for the patients with hypertension but the available evidences are uncertain. OBJECTIVE: We conducted a systematic review and meta-analysis, know the efficacy of foot reflexology on blood pressure reduction in patients with hypertension. DATA SOURCES AND SELECTION: A systematic search of electronic databases such as PubMed, Scopus, ClinicalTrials.gov, Embase, and Cochrane library since inception till January 2022. Randomized controlled trial with foot reflexology as an intervention for lowering blood pressure (BP) in hypertensive patients was included in the study. DATA EXTRACTION AND OUTCOME MEASURES: Data was independently extracted by four authors. Systolic and diastolic blood pressure was the primary outcome measure. Standardized mean difference (SMD) and 95 % confidence interval (CI) were calculated to determine the effect size. RESULTS: The pooled effect of SBP (SMD: -2.70, 95 % of CI: -6.79, 1.39, I2 - 97 %, P < 0.001) and DBP (SMD: -2.12, 95 % of CI: -5.95, 1.71, I2 - 97 %, P < 0.001) changes are not favorable for foot reflexology in terms of reducing blood pressure. CONCLUSION: Findings from the studies showed that foot reflexology interventions were not much effective in the reduction of blood pressure among patients with hypertension.

Preoperative neutrophil-lymphocyte ratio/platelet-lymphocyte ratio: A potential and economical marker for renal cell carcinoma.

Background: Emerging evidences have elucidated the crucial role of inflammation in carcinogenesis and tumor progression. In the recent years, many inflammatory biomarkers showed promising prognostic factors in renal cell carcinoma (RCC). We intended to evaluate the significance of one such inflammatory factor which is potential, noninvasive, simple, as well as economical. The preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in RCC patients have shown favorable results. Objective: The objective was to assess the prognostic role of NLR/PLR in the advanced stage and high-grade RCC. Subjects and Methods: This is a retrospective study. Ethical clearance was obtained from the institute ethics committee. One hundred and fifty histopathologically proven RCC cases during the period of January 2010-September 2018 were chosen from the pathology department and corresponding blood reports were obtained from the medical records department. We divided the cases based on their staging and grading. NLR/PLR values were calculated using formulas. Statistical Analysis: Statistical analysis was done using R software. Data were expressed as mean ± standard deviation, median, and percentage. Independent t-test, Mann-Whitney test, and Chi-square test were used. P < 0.05 was considered statistically significant. The receiver operating characteristic curve (ROC) was plotted to assess the sensitivity of NLR/PLR. Results: The elevated NLR/PLR values showed a significant relation with high-grade and advanced stage RCC. The ROC curve proved the accuracy of NLR/PLR in the advanced stage and high-grade RCC. Limitations: A multicentric, prospective study can be planned in the future. Follow-up studies are needed to assess their prognostic role. Conclusion: NLR/PLR values can become part of routine investigations for all RCC patients. The values may help to estimate pathological outcomes, chance of recovery, recurrence, and survival rates.

Effect of long-term yoga training on autonomic function among the healthy adults.

Background: Autonomic dysfunction is one of the major complications in noncommunicable diseases, and there are studies to prove yoga practice improves cardiac autonomic function. So, this present study was done to compare the autonomic functions among yoga practitioners and nonyoga practitioners. Methods: This cross-sectional comparative study was initiated among 68 healthy volunteers of both sexes, after recruiting them based on inclusion and exclusion criteria in the age group of 17-30 yrs. The autonomic reactivity tests like resting heart rate, response of heart rate to standing, Valsalva maneuver, and response of heart rate to deep breathing, response of BP to standing, and sustained hand-grip were done. Results: In the autonomic reactivity test, resting heart rate (80.92 ± 11.76 vs 69.24 ± 10.64) and sustained handgrip (16.30 ± 4.53 vs 10.20 ± 3.67) significantly decreased (P < 0.05) in the participants of the yoga group compared to control group. Deep breathing test, Valsalva maneuver, 30:15 ratio in lying to standing, and BP response to standing test did not show any significant difference between the groups (P > 0.05). Conclusion: The present study revealed diminished sympathetic activity and improved parasympathetic activity among the regular yoga practicing participants. It can be practiced regularly to reduce stress and prevent lifestyle-associated disorders in the future.

Prevalence of vitamin D deficiency among South Indian pregnant women.

Background: Deficiency of vitamin D is widespread across the globe. Expectant women are one of the most vulnerable groups for vitamin D deficiency (VDD). Even in South India with abundance of sunlight, pregnant women are believed to be at a high risk of this deficiency. The objectives of this study are to assess the prevalence of VDD in antenatal women, associate it with modifiable risk factors and evaluate its correlation with low birth weight. Methods: This cross-sectional study was conducted in a tertiary care hospital, in Chennai, in 100 pregnant women in their last trimester on the basis of inclusion and exclusion criteria and their vitamin D and calcium levels were assessed. A detailed history regarding physical activity, diet, and sun exposure were collected and results were analyzed. Results: The point prevalence of VDD (serum 25-hydroxyvitamin D (25(OH) D) level <20 ng/mL) among antenatal women in our study is 62%. Univariate analysis revealed that sun exposure and socioeconomic status were the significant factors associated with higher percentage of VDD. Linear regression analysis showed that only sun exposure was a significant predictor for serum 25(OH) D levels. VDD is also associated with increased risk of low-birth-weight babies. Conclusion: VDD is highly prevalent among pregnant women in South India leading to adverse health consequences in the mother and offspring. Less physical activity, decreased sun exposure, darker skin complexion, lower socioeconomic status and lack of awareness are the major risk factors associated with VDD in our study population.

Effects of 12 sessions of steam bath intervention on spirometry parameters among healthy adult volunteers.

OBJECTIVES: Steam bath is extensively used around the world. However, its physiological influence is not understood in detail. Objective of the current study is to examine the effects of 12 sessions of steam bath on spirometric parameters among healthy participants. METHODS: Forty healthy adult volunteers of both sex (14 male and 26 female) aged 26.38 ± 8 years participated in the study. A steam bath session (10-15 min) was given once a week for 12 weeks. The spirometric parameters [forced expiratory volume in the 1st second (FEV1, L), forced vital capacity (FVC, L), FEV1/FVC ratio (absolute value), maximal mid-expiratory flow (MMEF, L/s) and peak expiratory flow (PEF, L/s)] were measured by Helios 401 spirometer. RESULTS: Compared to baseline, post-intervention spirometric parameters showed significant (p<0.05) improvement in the FVC (82.40 ± 11.24 to 96.91 ± 18.76), FEV1 (86.13 ± 14.39 to 91.17 ± 12.48), FEV1/FVC ratio (86.96 ± 3.64 to 93.75 ± 4.80), MMEF 25-75% (86.96 ± 3.64 to 94.16 ± 11.57), peak expiratory flow rate (79.82 ± 14.90 to 92.18 ± 18.96). CONCLUSIONS: Taking steam bath improves the spirometric parameters of healthy adult participants. However, future randomized controlled trials with on a large scale have to done to validate our findings.

Immediate effects of the practise of Sheethali pranayama on heart rate and blood pressure parameters in healthy volunteers.

OBJECTIVES: Sheetali pranayama, a cooling pranayama is best known for its calming and relaxing nature, widely used for many conditions like depression, anxiety and hypertension. The aim of the study was to evaluate the immediate effect of the practice of Sheetali pranayama on heart rate and blood pressure parameters in healthy volunteers. METHODS: Apparently, 60 healthy volunteers were involved, from both sexes. They were split into pranayama (n=30) and control (n=30) groups at random. Sheetali pranayama was performed for 5 min (5 cycles) in the pranayama group and normal breathing (12-16 breaths/min) was permitted in the control group. Heart rate (HR) and blood pressure (BP) were recorded with RMS polyrite in the supine position after 5 min of rest. RESULTS: The HR in the pranayama group significantly decreased (p=0.04). Systolic (SBP) and diastolic blood (DBP) pressure, pulse pressure (PP) and mean arterial pressure (MAP) decreased significantly (p<0.05) relative to control after pranayama practice. Pre-Post inter-group results has also shown that the pranayama group has substantially decreased HR and BP indices. CONCLUSIONS: Present study shows that the practice of Sheetlai pranayama creates a relaxed state, and parasympathetic activity overrides sympathetic activity in this state. It indicates that in healthy volunteers, pranayama strengthens the resting cardiovascular parameters.

Effect of Yoga on Oxidative Stress in Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis.

BACKGROUND: Diabetes mellitus has a significant impact on public health. Oxidative stress plays a major role in the pathophysiology of Type 2 Diabetes Mellitus (T2DM), leading to various complications of T2DM. Yoga is being widely used in the management of T2DM. The primary objective of this systematic review and meta-analysis is to understand the effects of yoga on oxidative stress parameters among adult patients diagnosed with T2DM. MATERIALS AND METHODS: Electronic databases such as PubMed, Scopus, Cochrane Library and Science Direct from start of the study till March 2020 were searched to obtain eligible studies. Study designs of all nature were included (except case studies and reviews). The primary outcome was Malondialdehyde (MDA) and secondary outcomes included fasting plasma glucose, HbA1C and Superoxide Dismutase (SOD) levels. RESULTS: A total of four trials with a total of 440 patients met the inclusion criteria. The results of meta-analysis indicated that yoga significantly reduced MDA (SMD: -1.4; 95% CI -2.66 to -0.13; P = 0.03; I2 = 97%), fasting plasma glucose levels (SMD: -1.87: 95% CI -3.83 to -0.09; P = 0.06; I2= 99%), and HbA1c (SMD: -1.92; 95% CI - 3.03 to -0.81; P = 0.0007; I2 = 92%) in patients with T2DM. No such effect was found for SOD (SMD: -1.01; 95% CI -4.41 to 2.38; P = 0.56; I2= 99%). CONCLUSION: The available evidence suggests that yoga reduces MDA, fasting plasma glucose and HbA1C, and thus would be beneficial in the management of T2DM as a complementary therapy. However, considering the limited number of studies and its heterogeneity, further robust studies are necessary to strengthen our findings and investigate the long-term benefits of yoga.

Effect of six months pranayama training on stress-induced salivary cortisol response among adolescents-Randomized controlled study.

BACKGROUND: A combination of yoga practices has been documented to reduce stress and stress-induced cortisol levels. The objective of the current study is to examine the effects of six months of a single pranayama practice (Bhramari [Bhr. P]) on reducing salivary cortisol response to the cold pressor test (CPT) among adolescents. METHODS: Twenty-six healthy adolescents between the ages of 11 and 19 were randomly assigned to either yoga group (n-13) or control group (n-13). Yoga group participants were trained to do Bhr. P for 45 min, thrice a week for six months. All participants underwent CPT at baseline and at end of six months. Saliva samples were collected at baseline (t0), at 20 min (t1), 40 min (t2), and 60 min after the CPT (t3). RESULTS: Contradictory to our hypothesis, participants in the yoga group exhibited a higher salivary cortisol response to the CPT at t1 (p = 0.04) when compared to the control group. However, the t3 salivary cortisol levels showed a statistically significant reduction (p = 0.03) in yoga group when compared to the control group. A significant interaction with time (F (1, 88) = 316.5, p = .001, ηp2:0.91) and between the group × time (F (3, 88) = 2.83, p = 0.04, ηp2:0.8) was found after the intervention. CONCLUSIONS: An increase in the cortisol responsiveness observed in the study is an indication of the adaptive capability achieved through regular yoga training, evidenced by an initial rise in cortisol followed by a rapid fall below baseline after 60 min. Further research is required to conclusively determine the changes in cortisol levels over time in response to stress in long-term yoga practitioners.

Validation of Internal structure of Self-Directed Learning Readiness Scale among Indian Medical Students using factor analysis and the Structural equation Modelling Approach.

BACKGROUND: The Self-Directed Learning Readiness Scale (SDLRS) is a tool that helps in the assessment of the readiness of the students to pursue Self-Directed Learning (SDL). There are no documented studies on the validation of internal structure of the SDLRS among Indian medical students. Hence, the objective of this study is to validate the internal structure of SDLRS among Indian medical students using factor analysis and the Structural Equation Modelling (SEM) approach. METHODS: We administered Fisher's 40-item SDLRS to 750 students after receiving the ethics clearance and the author's permission and taking written informed consent from all the study participants (response rate: 92%). The exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Cronbach's alpha were performed using SPSS version 25 and the Lavaan package of R version 3.1.2. RESULTS: The values of the comparative fit index (CFI), standardised root-mean-square residual (SRMR), and root mean square error of approximation (RMSEA) were ≥ 0.9, ≤ 0.08, and ≤ 0.08, respectively, for a model fit to be acceptable. EFA showed that except for Q2 (loading score: 0.210), Q12 (loading score: 0.384), Q13 (loading score: 0.362), and Q25 (loading score: -0.219), all the items loaded well. After the exclusion of the aforementioned items, the factor loading scores for the items in the self-management, desire for learning, and self-control factors ranged from 0.405 to 0.753 (Cronbach α: 0.775), 0.396 to 0.616 (Cronbach α: 0.730), and 0.427 to 0.556 (Cronbach α: 0.799), respectively. The updated model was used for CFA, which displayed a good model fit. CONCLUSIONS: The resultant model consisting of 36 items is shown to have internal structure validity for Indian version of SDLRS, which can be used to assess medical students.

Utilization Trends and Predictors of Non-invasive and Invasive Ventilation During Hospitalization Due to Community-Acquired Pneumonia.

BACKGROUND: Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality. Non-invasive ventilation (NIV) and invasive mechanical ventilation (IMV) are most important interventions for patients with severe CAP associated with respiratory failure. We analysed utilization trends and predictors of non-invasive and invasive ventilation in patients hospitalized with CAP. METHODS:  Nationwide Inpatient Sample and Healthcare Cost and Utilization Project data for years 2008-2017 were analysed. Adult hospitalizations due to CAP were identified by previously validated International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) and International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes. We then utilized the Cochran-Armitage trend test and multivariate survey logistic regression models to analyse temporal incidence trends, predictors, and outcomes. We used SAS 9.4 software (SAS Institute Inc., Cary, NC, USA) for analysing data. RESULTS: Out of a total of 8,385,861 hospitalizations due to CAP, ventilation assistance was required in 552,395 (6.6%). The overall ventilation use increased slightly; however, IMV utilization decreased, while NIV utilization increased. In multivariable regression analysis, males, Asian/others and weekend admissions were associated with higher odds of any ventilation utilization. Concurrent diagnoses of septicemia, congestive heart failure, alcoholism, chronic lung diseases, pulmonary circulatory diseases, diabetes mellitus, obesity and cancer were associated with increased odds of requiring ventilation assistance. Ventilation requirement was associated with high odds of in-hospital mortality and discharge to facility. CONCLUSION: The use of NIV among CAP patients has increased while IMV use has decreased over the years. We observed numerous factors linked with a higher use of ventilation support. The requirement of ventilation support is also associated with very high chances of mortality and morbidity.

Evaluation of workshop on teaching skills for medical postgraduates (Ramachandra Annual Postgraduate Teaching Skills).

BACKGROUND: Postgraduate medical curriculum is usually devoted to developing competencies in the specialty concerned, patient care, and submitting dissertations. The need to impart teaching skills during postgraduation has gone unnoticed, hence Ramachandra Annual Postgraduate Teaching Skills (RAPTS), a teaching skills workshop, was conceptualized and implemented as postgraduate students serve as tutors/residents in the department to teach undergraduate medical students. This study is aimed to evaluate the effectiveness of the teaching skills workshop for postgraduates. MATERIALS AND METHODS: One hundred and seventy-eight postgraduate students of pre- and paraclinical department underwent the training in medical education principles and participated in the feedback. RAPTS Workshop was implemented as per the six-step approach. The learning was evaluated through a pre- and posttest scores. Student feedback was also obtained on the process overall objectives and contents of the workshop. Force-field analysis was performed. RESULTS: There was a significant learning by the postgraduates on various medical education principles as evidenced by significant improvement in the posttest scores (P < 0.05). Feedback regarding the general aspects of the workshop showed that 92% of the participants felt that the contents of the workshop suited their learning. Eighty-four percent of the participants opined that the presentations of the sessions were good and 91% felt that time management was good. Force-field analysis indicated that the factors favoring teaching skills workshop were higher. CONCLUSION: This study has highlighted the importance of including teaching methodology training in the postgraduate curriculum that helps in grooming the future teachers in the right direction, in the right time. Competencies related to teaching skills based on medical education principles can be included in the postgraduate curriculum.

Yoga and Naturopathy intervention for reducing anxiety and depression of Covid-19 patients - A pilot study.

BACKGROUND: Coronavirus disease 2019 (Covid-19) infection has caused a prominent psychological and mental havoc among the patients. Till now, there is paucity in literature for the management of psychological problems among patients with Covid-19. So we aimed in our study to assess the effect of Yoga and Naturopathy intervention on anxiety and depression of Covid-19 patients. METHODS: This quasi experimental study was conducted among 130 Covid-19 positive patients admitted in a tertiary care hospital. Yoga and Naturopathic intervention was given for 60 min a day for two weeks. Hospital anxiety depression scale (HADS) and Corona anxiety scale (CAS) was used to assess the generalized anxiety and depression among the patients. RESULTS: Average age of the patients participated was 44 with the range from 36 to 53 years. Among them 85 were male and 45 were female. Of all 130 patients, 33% had symptoms of borderline depression, 9.2% had severe depression, 40% had borderline anxiety and 12.3% had severe anxiety. In CAS, 59 patients (45.38%) reported Covid-19 related dysfunctional anxiety. All the patients showed a significant reduction in the HADS- anxiety (P < 0.01), HADS-depression (p < 0.01) and CAS (p < 0.01) score after the intervention. CONCLUSION: The present study showed significant reduction of anxiety and depression level among the Covid-19 patients. These interventions can be added to the conventional care for better mental and physical wellbeing of the patients after validating the findings with justified study design.

Development and validation of a structured feedback questionnaire from postgraduates on various elements of postgraduate medical curriculum.

BACKGROUND: Medical Council of India, introduced the Post Graduate (PG) curriculum as 'Competency Based Medical Education' (CBME). Feedback from the end users is a vital step in curriculum evaluation. Therefore, the primary objective of this study was to develop and validate a Structured Feedback Questionnaire (SFQ) for postgraduates, encompassing all the components of the PG-CBME curriculum. METHODS: SFQ was developed with 23 Likert based questions and four open ended questions. Content validation was done by Lawshe method. After getting institutional ethics clearance and informed consent, SFQ was administered to 121 final year PGs (response rate 100%). We performed Principal component analysis (PCA), Structural equation modeling (SEM), Chi squared test (χ2/df); goodness-of-fit index (GFI); adjusted GFI; comparative fit index (CFI) and root mean square error of approximation (RMSEA). Cronbach's alpha was done for estimating the internal consistency. RESULTS: The validation resulted in a three-factor model comprising of "curriculum" (42.1%), "assessment" (28%), and "support" (18.5%). Chi squared test (χ2/df ratio) < 2, CFI (0.78), GFI (0.72) and RMSEA (0.09) indicated superior goodness of fit for the three-factor model for the sample data. All the extracted factors had good internal consistency of ≥0.9. CONCLUSION: We believe that this 23 item SFQ is a valid and reliable tool which can be utilized for curriculum evaluation and thereby formulating recommendations to modify the existing curriculum wherever required, facilitating enriched program outcomes.
