Ayurveda concept of Yoga Chakras and their Anatomical aspects

The ancient texts of Ayurveda and various yoga traditions referred term Chakra which indicates energy centre. The word Chakra means itself says about the wheel which circulates energy and governs many physiological processes inside the body. The blockage of Chakra causes abnormal physiology inside the body. Chakras are responsible for positive influence and induce natural healing process of body. Chakras contributed towards the spiritual and moral conducts of individuals. The flow of energies maintained by Chakras provide internal and as well as psychic strength. Root Chakra, Sacral Chakra, Solar Plexus Chakra, Heart Chakra, Throat Chakra, Third Eye Chakra and Crown Chakra are major seven Chakras of body within which the Vishwaprana (universal life force) flows

Therapeutic Drug Monitoring of Anti-infective Drugs:Implementation Strategies for 3 Different Scenarios

BACKGROUND: Therapeutic drug monitoring (TDM) supports personalized treatment. For successful implementation, TDM must have a turnaround time suited to the clinical needs of patients and their health care settings. Here, the authors share their views of how a TDM strategy can be tailored to specific settings and patient groups. METHODS: The authors selected distinct scenarios for TDM: high-risk, complex, and/or critically ill patient population; outpatients; and settings with limited laboratory resources. In addition to the TDM scenario approach, they explored potential issues with the legal framework governing dose escalation. RESULTS: The most important issues identified in the different scenarios are that critically ill patients require rapid turnaround time, outpatients require an easy sampling procedure for the sample matrix and sample collection times, settings with limited laboratory resources necessitate setting-specific analytic techniques, and all scenarios warrant a legal framework to capture the use of escalated dosages, ideally with the use of trackable dosing software. CONCLUSIONS: To benefit patients, TDM strategies need to be tailored to the intended population. Strategies can be adapted for rapid turnaround time for critically ill patients, convenient sampling for outpatients, and feasibility for those in settings with limited laboratory resources

Levofloxacin pharmacokinetics in saliva as measured by a mobile microvolume UV spectrophotometer among people treated for rifampicin-resistant TB in Tanzania

Background: Early detection and correction of low fluoroquinolone exposure may improve treatment of MDR-TB. Objectives: To explore a recently developed portable, battery-powered, UV spectrophotometer for measuring levofloxacin in saliva of people treated for MDR-TB. Methods: Patients treated with levofloxacin as part of a regimen for MDR-TB in Northern Tanzania had serum and saliva collected concurrently at 1 and 4 h after 2 weeks of observed levofloxacin administration. Saliva levofloxacin concentrations were quantified in the field via spectrophotometry, while serum was analysed at a regional laboratory using HPLC. A Bayesian population pharmacokinetics model was used to estimate the area under the concentration-time curve (AUC(0-24)). Subtarget exposures of levofloxacin were defined by serum AUC(0-24) Results: Among 45 patients, 11 (25.6%) were women and 16 (37.2%) were living with HIV. Median AUC(0- 24) in serum was 140 (IQR = 102.4-179.09) mg.h/L and median AUC(0- 24) in saliva was 97.10 (IQR = 74.80-121.10) mg.h/L. A positive linear correlation was observed with serum and saliva AUC(0-24), and a receiver operating characteristic curve constructed to detect serum AUC(0- 24) below 80mg.h/L demonstrated excellent prediction [AUC 0.80 (95% CI = 0.62-0.94)]. Utilizing a saliva AUC(0- 24) cut-off of 91.6mg.h/L, the assay was 88.9% sensitive and 69.4% specific in detecting subtarget serum AUC(0- 24) values, including identifying eight of nine patients below target. Conclusions: Portable UV spectrophotometry as a point-of-care screen for subtarget levofloxacin exposure was feasible. Use for triage to other investigation or personalized dosing strategy should be tested in a randomized study

Alternative Methods for Therapeutic Drug Monitoring and Dose Adjustment of Tuberculosis Treatment in Clinical Settings: A Systematic Review

Background and objectiveQuantifying exposure to drugs for personalized dose adjustment is of critical importance in patients with tuberculosis who may be at risk of treatment failure or toxicity due to individual variability in pharmacokinetics. Traditionally, serum or plasma samples have been used for drug monitoring, which only poses collection and logistical challenges in high-tuberculosis burden/low-resourced areas. Less invasive and lower cost tests using alternative biomatrices other than serum or plasma may improve the feasibility of therapeutic drug monitoring.MethodsA systematic review was conducted to include studies reporting anti-tuberculosis drug concentration measurements in dried blood spots, urine, saliva, and hair. Reports were screened to include study design, population, analytical methods, relevant pharmacokinetic parameters, and risk of bias.ResultsA total of 75 reports encompassing all four biomatrices were included. Dried blood spots reduced the sample volume requirement and cut shipping costs whereas simpler laboratory methods to test the presence of drug in urine can allow point-of-care testing in high-burden settings. Minimal pre-processing requirements with saliva samples may further increase acceptability for laboratory staff. Multi-analyte panels have been tested in hair with the capacity to test a wide range of drugs and some of their metabolites.ConclusionsReported data were mostly from small-scale studies and alternative biomatrices need to be qualified in large and diverse populations for the demonstration of feasibility in operational settings. High-quality interventional studies will improve the uptake of alternative biomatrices in guidelines and accelerate implementation in programmatic tuberculosis treatment
