Item Isha Yoga Practices and Participation in Samyama Program are Associated with Reduced HbA1C and Systemic Inflammation, Improved Lipid Profile, and Short-Term and Sustained Improvement in Mental Health: A Prospective Observational Study of Meditators(Frontiers Media, 2021-05-19) Sadhasivam, Senthilkumar; Alankar, Suresh; Maturi, Raj; Williams, Amy; Vishnubhotla, Ramana V.; Hariri, Sepideh; Mudigonda, Mayur; Pawale, Dhanashri; Dubbireddi, Sangeeth; Packiasabapathy, Senthil; Castelluccio, Peter; Ram, Chithra; Renschler, Janelle; Chang, Tracy; Subramaniam, Balachundhar; Anesthesia, School of MedicineBackground: Meditation is gaining recognition as a tool to impact health and well-being. Samyama is an 8-day intensive residential meditation experience conducted by Isha Foundation requiring several months of extensive preparation and vegan diet. The health effects of Samyama have not been previously studied. The objective was to assess physical and emotional well-being before and after Samyama participation by evaluating psychological surveys and objective health biomarkers. Methods: This was an observational study of 632 adults before and after the Isha Samyama retreat. All participants were invited to complete surveys. Controls included household significant others. Surveys were completed at baseline (T1), just before Samyama (T2), immediately after Samyama (T3), and 3 months later (T4) to assess anxiety, depression, mindfulness, joy, vitality, and resilience through validated psychometric scales. Voluntary blood sampling for biomarker analysis was done to assess hemoglobin (Hb), HbA1c, lipid profile, and C-reactive protein (CRP). Primary outcomes were changes in psychometric scores, body weight, and blood biomarkers. Results: Depression and anxiety scores decreased from T1 to T3, with the effect most pronounced in participants with baseline depression or anxiety. Scores at T4 remained below baseline for those with pre-existing depression or anxiety. Vitality, resilience, joy, and mindfulness increased from T1 to T3 (sustained at T4). Body weight decreased by 3% from T1 to T3. Triglycerides (TG) were lower from T2 to T3. Participants had lower HbA1c and HDL at T2, and lower CRP at all timepoints compared with controls. Conclusions: Participation in the Isha Samyama program led to multiple benefits. The 2-month preparation reduced anxiety, and participants maintained lower anxiety levels at 3 months post-retreat. Physical health improved over the course of the program as evidenced by weight loss and improved HbA1C and lipid profile. Practices associated with the Samyama preparation phase and the retreat may serve as an effective way to improve physical and mental health. Future studies may examine their use as an alternative therapy in patients with depression and/or anxiety.Item Liposomal bupivacaine reduces opioid requirements following Ravitch repair for pectus excavatum(Wolters Kluwer, 2023) Abbasi, Rania K.; Cossu, Anne E.; Tanner, Brandon; Castelluccio, Peter; Hamilton, Matthew; Brown, John; Herrmann, Jeremy; Anesthesia, School of MedicineBackground and aims: The management of post-operative pain after surgical repair of pectus excavatum with the Ravitch procedure is challenging. Although previous studies have compared various methods of pain control in these patients, few have compared different local anesthetics. This retrospective analysis compares the use of bupivacaine to its longer-acting form, liposomal bupivacaine, in patients who had undergone pectus excavatum repair with the Ravitch method. Material and methods: Eleven patients who received local infiltration with liposomal bupivacaine were matched to 11 patients who received local infiltration utilizing bupivacaine with epinephrine. The primary outcome was total morphine milligram equivalents per kilogram body weight (MME/kg) over the complete length of hospital stay. Secondary outcomes included total cumulative diazepam, acetaminophen, ondansetron, and NSAID dose per kilogram body weight (mg/kg) over the course of the hospital stay, chest tube drainage (ml/kg body weight), number of post-operative hours until the first bowel movement, Haller Index, patient request for magnesium hydroxide, average pain scores from post-operative day 1 to post-operative day 5, and length of hospital stay. Continuous variables were reported as medians with inter-quartile ranges, and categorical values were reported as percentages and frequencies. Results: The total MME/kg [1.7 (1.2-2.4) vs 2.9 (2.0-3.9), P = 0.007] and hydromorphone (mg/kg) [0.1 (0.0-0.2) vs 0.3 (0.1-0.4), P = 0.006] use in the liposomal bupivacaine group versus bupivacaine with epinephrine was significantly reduced over total length of hospital stay. Similarly, there was a reduction in diazepam use in the liposomal bupivacaine group versus the bupivacaine group [0.4 (0.1-0.8) vs 0.6 (0.4-0.7), P = 0.249], but this did not reach statistical significance. The total dose of ondansetron (mg/kg) was not statistically different when comparing the liposomal bupivacaine group to the bupivacaine group [0.3 (0.0-0.5) vs 0.3 (0.2-0.6), P = 0.332]. Interestingly, the total dose of acetaminophen (mg/kg) was statistically increased in the liposomal bupivacaine group compared to the bupivacaine with epinephrine group [172 (138-183) vs 74 (55-111), P = 0.007]. Additionally, the total chest tube drainage (ml/kg) was significantly reduced in the liposomal bupivacaine group [9.3 (7.5-10.6) vs 12.8 (11.3-18.5), P = 0.027]. Finally, the percentage of patients without requests for magnesium hydroxide to promote laxation was significantly higher in the liposomal bupivacaine group than in the bupivacaine group (63.6% vs 18.2%, P = 0.027). Conclusion: The use of liposomal bupivacaine for local infiltration in patients who undergo the Ravitch procedure for pectus repair offers advantages over plain bupivacaine, including reduced opioid consumption and opioid-related side effects. However, more data are needed to understand the significance of these findings.Item Methadone-based Multimodal Analgesia Provides the Best-in-class Acute Surgical Pain Control and Functional Outcomes With Lower Opioid Use Following Major Posterior Fusion Surgery in Adolescents With Idiopathic Scoliosis(Wolters Kluwer, 2020-07-27) Ye, Jian; Myung, Karen; Packiasabapathy, Senthil; Yu, Jeffrey S.; Jacobson, Joseph E.; Whittaker, Stephanie C.; Castelluccio, Peter; Drayton Jackson, Meghan; Sadhasivam, Senthilkumar; Anesthesia, School of MedicineIntroduction: Posterior spinal fusion for idiopathic scoliosis is extremely painful, with no superior single analgesic modality. We introduced a methadone-based multimodal analgesia protocol, aiming to decrease the length of hospital stay (LOS), improve pain control, and decrease the need for additional opioids. Methods: We analyzed 122 idiopathic scoliosis patients with posterior instrumented spinal fusion. They were matched by age, sex, surgeon, and the number of levels fused before and after the implementation of the new protocol. This analysis included 61 controls (intrathecal morphine, gabapentin, intravenous opioids, and adjuncts) and 61 patients on the new protocol (scheduled methadone, methocarbamol, ketorolac/ibuprofen, acetaminophen, and oxycodone with intravenous opioids as needed). The primary outcome was LOS. Secondary outcomes included pain scores, total opioid use (morphine milligram equivalents), time to a first bowel movement, and postdischarge phone calls. Results: New protocol patients were discharged earlier (median LOS, 2 days) compared with control patients (3 days; P < 0.001). Total inpatient morphine consumption was lower in the protocol group (P < 0.001). Pain scores were higher in the protocol group on the day of surgery, similar on postoperative day (POD) 1, and lower by POD 2 (P = 0.01). The new protocol also reduced the median time to first bowel movement (P < 0.001), and the number of postdischarge pain-related phone calls (P < 0.006). Conclusion: Methadone-based multimodal analgesia resulted in significantly lower LOS compared with the conventional regimen. It also provided improved pain control, reduced total opioid consumption, and early bowel movement compared with the control group.Item Relationship of Hippocampal Volume to Amyloid Burden across Diagnostic Stages of Alzheimer’s Disease(Karger, 2016-03) Trzepacz, Paula T.; Hochstetler, Helen; Yu, Peng; Castelluccio, Peter; Witte, Michael M.; Dell'Agnello, Grazia; Degenhardt, Elisabeth; Department of Psychiatry, IU School of MedicineAims: To assess how hippocampal volume (HV) from volumetric magnetic resonance imaging (vMRI) is related to the amyloid status at different stages of Alzheimer's disease (AD) and its relevance to patient care. Methods: We evaluated the ability of HV to predict the florbetapir positron emission tomography (PET) amyloid positive/negative status by group in healthy controls (HC, n = 170) and early/late mild cognitive impairment (EMCI, n = 252; LMCI, n = 136), and AD dementia (n = 75) subjects from the Alzheimer's Disease Neuroimaging Initiative Grand Opportunity (ADNI-GO) and ADNI2. Logistic regression analyses, including elastic net classification modeling with 10-fold cross-validation, were used with age and education as covariates. Results: HV predicted amyloid status only in LMCI using either logistic regression [area under the curve (AUC) = 0.71, p < 0.001] or elastic net classification modeling [positive predictive value (PPV) = 72.7%]. In EMCI, age (AUC = 0.70, p < 0.0001) and age and/or education (PPV = 63.1%), but not HV, predicted amyloid status. Conclusion: Using clinical neuroimaging, HV predicted amyloid status only in LMCI, suggesting that HV is not a biomarker surrogate for amyloid PET in clinical applications across the full diagnostic spectrum.
