Wellness or medicine? Use and perception of Ayurveda in Germany: data from an online-representative cross-sectional study.

Introduction: Ayurveda, South Asia's largest and most relevant system of Traditional Medicine, holds a legal status akin to conventional Western medicine in India and elsewhere. There is an almost complete lack of data on the use of Ayurveda in Germany. The aim of this study was to investigate Ayurveda's utilization patterns, entry points, and factors influencing its use and the perception of Ayurveda among the German population. Methods: Basis of this manuscript was an online-representative survey which involved 4,065 participants aged 18-75 about the use and acceptance of Traditional, Complementary and Integrative Medicine (TCIM) in Germany. The survey was conducted online using Computer Assisted Web Interview (CAWI) in 2022. The dataset was analyzed descriptively and inferentially. Results: Altogether 9.3% (n = 377) of all survey participants (n = 4,065) had already used Ayurveda somehow, either more often (1.7%) or at least once in a lifetime (7.6%). Responders associated Ayurveda primarily with Indian Medicine (27.7%) and wellness (18%). Commonly used Ayurvedic services included non-medical treatments at wellness resorts/spas (48.3%), in outpatient practices (27.1%), and hotels (23.6%). 30.2% of the participants believe in Ayurveda's therapeutic potential. 76.7% of Ayurveda users find healthy nutrition important or very important. Nine predictors were found to classify Ayurveda users vs. non-users with spirituality and belief in Ayurveda's therapeutic efficacy as the most relevant ones. Ayurveda seems to be primarily used by well-educated and female individuals, often from higher-income groups and with a rather modern social milieu-orientation. Conclusion: Study results suggest that about every tenth German citizen has used Ayurveda in the past and about one third believes in its therapeutic potential. Because Ayurvedic therapies are often not evidence-based, there is an urgent need to perform high quality randomized controlled trials to investigate potential effects and safety of Ayurveda and how evidence-based Ayurveda treatments can be integrated into the German healthcare system.

Venetoclax Clinical Pharmacokinetics After Administration of Crushed, Ground or Whole Tablets.

PURPOSE: Venetoclax is a potent, orally bioavailable BCL-2 inhibitor used in the treatment of some hematological malignancies. Crushing tablets may be necessary to help with the administration of venetoclax to patients with swallowing difficulties or patients requiring nasogastric tube feeding. The study was conducted to assess the bioavailability of crushed and finely ground venetoclax tablets relative to whole tablets. METHODS: An open-label, randomized, 3-way, crossover study in 15 healthy adult females was conducted. Venetoclax tablets were administered orally in a crushed, ground or intact form on Day 1 of each period with water following a high-fat breakfast. Pharmacokinetic samples were collected up to 72 hours postdosing. FINDINGS: The crushed and ground tablets met the bioequivalence criteria (0.80-1.25) relative to the intact tablets with respect to area under the concentration-time curve to time of the last measurable concentration (AUCt) and to infinite time (AUCinf) but exhibited a slightly lower maximum plasma concentration (Cmax). This was not considered clinically significant as only venetoclax overall exposure (AUC) has been shown to correlate with clinical efficacy. There was no change in the physical appearance and the evaluated physicochemical properties of crushed and ground venetoclax tablets after 72 hours of storage at 25°C/60% relative humidity. IMPLICATIONS: Crushing or grinding venetoclax tablets before administration could be considered as a viable alternative method of administration for patients who have difficulty swallowing whole venetoclax tablets or patients requiring nasogastric tube feeding.

Interventions to reduce stress and prevent burnout in healthcare professionals supported by digital applications: a scoping review.

Aim: Healthcare professionals are at increased risk of burnout, primarily due to workplace-related stressors. The COVID-19 pandemic has further increased this risk. Different interventions exist with varying degrees of effectiveness; little is reported on the content and implementation of such programs. This review fills this gap, with attention to recent programs using digital components. Methods: PubMed, Embase, PsycInfo, and Google Scholar were searched between January 24th and 28th, 2022, limited to the last 5 years (≥2017). Articles were included if they (1) focused on stress reduction or burnout prevention for nurses and medical doctors within workplace health promotion for nurses or medical doctors, (2) included a digital program component, (3) were conducted in high-income country contexts, and (4) were clinical studies published in English or German. Data was extracted using a priori designed spreadsheets. A group of at least 2 authors at each stage carried out the screening, selection, and data extraction. Results: The search strategy identified 153 articles, all except 7 were excluded. Two studies were conducted in the USA, two in Spain, one in the Netherlands, Poland, and Korea each. Four studies used a randomized study design, all but one had a control group. A wide range of outcome measures was used. The types of interventions included an adapted mindfulness-based stress reduction program combined with aspects of behavioral therapies, cognitive behavioral therapy, or acceptance and commitment therapy. The digital components used were apps (4 studies), a digital platform, blended learning, and a web-based intervention (1 study each). Six studies focused on individual interventions, one included organizational interventions. Conclusion: Despite an acute burnout crisis in the healthcare sector, only seven recent interventions were found that integrated digital components. Several problems emerged during the implementation of the interventions that made it clear that organizational support is urgently needed for successful implementation. Although interventions for stress reduction and burnout prevention should combine individual and organizational measures to be as successful as possible, this was only partially the case in one of the intervention programs. The results of this scoping review can be used to further develop or optimize stress and burnout prevention programs.

Application of biorelevant in vitro assays for the assessment and optimization of ASD-based formulations for pediatric patients.

Amorphous solid dispersions (ASD) have been a successful formulation strategy to overcome the poor aqueous solubility of many novel drugs, but the development of pediatric formulations presents a special challenge due to variable gastrointestinal conditions in children. It was the aim of this work to design and apply a staged biopharmaceutical test protocol for the in vitro assessment of ASD-based pediatric formulations. Ritonavir was used as a model drug with poor aqueous solubility. Based on the commercial ASD powder formulation, a mini-tablet and a conventional tablet formulation were prepared. Drug release from the three formulations was studied in different biorelevant in vitro assays (i.e. MicroDiss, two-stage, transfer model, tiny-TIM) to consider different aspects of human GI physiology. Data from the two-stage and transfer model tests indicated that by controlled disintegration and dissolution excessive primary precipitation can be prevented. However, this advantage of the mini-tablet and tablet formulation did not translate into better performance in tiny-TIM. Here, the in vitro bioaccessibility was comparable for all three formulations. In the future, the staged biopharmaceutical action plan established herein will support the development of ASD-based pediatric formulations by improving the mechanistic understanding so that formulations are developed for which drug release is robust against variable physiological conditions.

Bioavailability Evaluation of Venetoclax Lower-Strength Tablets and Oral Powder Formulations to Establish Interchangeability with the 100 mg Tablet.

BACKGROUND AND OBJECTIVE: Venetoclax is an approved BCL-2 inhibitor, currently under evaluation in different hematological malignancies in adult and pediatric populations. Venetoclax is available as 10, 50, and 100 mg tablets. To provide an alternative to patients who find taking the commonly prescribed 100 mg tablet a challenge, the interchangeability of lower-strength tablets with the 100 mg tablet was investigated. Additionally, newly developed oral suspension powder formulations to facilitate dosing in pediatrics were evaluated. METHODS: Pharmacokinetic data from 80 healthy female participants from three phase I studies were utilized to evaluate the bioavailability of (1) 10 and 50 mg tablets relative to a 100 mg tablet; (2) 0.72 and 7.2% (drug to total weight) oral powder formulations relative to the 100 mg tablet; and (3) oral powder formulations administered using different vehicles (apple juice, apple sauce, and yogurt) relative to water under fed conditions. RESULTS: Bioavailability assessments at a 100 mg dose of venetoclax demonstrated bioequivalence across the 10, 50, and 100 mg tablet strengths. Oral powder formulations met the bioequivalence criteria (0.80-1.25) with respect to area under the concentration-time curve to time of the last measurable concentration (AUCt) and to infinite time (AUC∞) but exhibited a slightly lower maximum plasma concentration (Cmax). Exposure-response analyses were utilized to demonstrate that the lower Cmax observed with the powder formulations is not clinically meaningful. The delivery vehicles tested did not affect the bioavailability of venetoclax oral powder formulations. CONCLUSIONS: The smaller-sized tablets (10 and 50 mg) and the newly developed oral powder formulations of venetoclax can be used interchangeably with the 100 mg tablets to improve the patients' experience, while maintaining adequate exposure.

Proposed Tool to Compare and Assess the Applicability of Taste Assessment Techniques for Pharmaceuticals.

Palatability is amongst the most important determinants of whether or not a child will take a medicine. In order to increase concordance with treatment regimens it is often necessary to utilise a range of formulation techniques to improve the palatability of medicines. These can include selecting a different molecule or version of a molecule (such as a different polymorph or salt form), various taste masking techniques and/or the inclusion of flavours and sweeteners. In order to be able to understand the taste of the Active Pharmaceutical Ingredient (API) and to validate the formulation approach used, it is necessary to be able to use the most reliable taste evaluation method possible. Multiple in vivo and in vitro methods exist nowadays or are proposed in the literature but are often little understood by the pharmaceutical product development community. In particular, different methods may be more relevant at different stages of product development. The aim of this article is to propose a tool to guide the selection of the most appropriate method for the desired evaluation. A spreadsheet-based tool is proposed that is designed to allow the systematic assessment of the applicability of any taste assessment technique existing or new to the users proposed application. A series of criteria are defined that will allow the user to assess the analytical, usability and availability factors for the technique that is being considered. Such a systematic review will help the user to understand the benefits and risks of using each methodology for that application. The use of the tool is illustrated based on currently available data and literature. As new/existing methods are developed/improved, the outcomes of the tool may change.

Swallowing Tablets and Capsules Increases the Risk of Penetration and Aspiration in Patients with Stroke-Induced Dysphagia.

We evaluated the prevalence of difficulties swallowing solid dosage forms in patients with stroke-induced dysphagia and whether swallowing tablets/capsules increases their risk of penetration and aspiration. Concurrently, we explored whether routinely performed assessment tests help identify patients at risk. Using video endoscopy, we evaluated how 52 patients swallowed four different placebos (round, oval, and oblong tablets and a capsule) with texture-modified water (TMW, pudding consistency) and milk and rated their swallowing performance according to the Penetration Aspiration Scale (PAS). Additionally, Daniels Test, Bogenhausener Dysphagiescore, Scandinavian Stroke Scale, Barthel Index, and Tinetti's Mobility Test were conducted. A substantial proportion of the patients experienced severe difficulties swallowing solid oral dosage forms (TMW: 40.4 %, milk: 43.5 %). Compared to the administration of TMW/milk alone, the placebos increased the PAS values in the majority of the patients (TMW: median PAS from 1.5 to 2.0; milk: median PAS from 1.5 to 2.5, each p value <0.0001) and residue values were significantly higher (p < 0.05). Whereas video-endoscopic examination reliably identified patients with difficulties swallowing medication, neither patients' self-evaluation nor one of the routinely performed bedside tests did. Therefore, before video-endoscopic evaluation, many drugs were modified unnecessarily and 20.8 % of these were crushed inadequately, although switching to another dosage form or drug would have been possible. Hence, safety and effectiveness of swallowing tablets and capsules should be evaluated routinely in video-endoscopic examinations, tablets/capsules should rather be provided with TMW than with milk, and the appropriateness of "non per os except medication" orders for dysphagic stroke patients should be questioned.

Two techniques to make swallowing pills easier.

To evaluate whether 2 techniques (the pop-bottle method for tablets and the lean-forward technique for capsules) ease swallowing of tablets and capsules, we conducted a cross-sectional study including 151 adults of the general German population. Participants swallowed 16 differently shaped placebos, rated their ease of swallowing on an 8-point Likert scale, and swallowed the 2 dosage forms that they had rated most difficult again using the appropriate technique. The pop-bottle method substantially improved swallowing of tablets in 59.7% (169/283) and the lean-forward technique for capsules in 88.6% (31/35). Both techniques were remarkably effective in participants with and without reported difficulties swallowing pills and should be recommended regularly.

Safeguarding the process of drug administration with an emphasis on electronic support tools.

AIMS: The aim of this work is to understand the process of drug administration and identify points in the workflow that resulted in interventions by clinical information systems in order to improve patient safety. METHODS: To identify a generic way to structure the drug administration process we performed peer-group discussions and supplemented these discussions with a literature search for studies reporting errors in drug administration and strategies for their prevention. RESULTS: We concluded that the drug administration process might consist of up to 11 sub-steps, which can be grouped into the four sub-processes of preparation, personalization, application and follow-up. Errors in drug handling and administration are diverse and frequent and in many cases not caused by the patient him/herself, but by family members or nurses. Accordingly, different prevention strategies have been set in place with relatively few approaches involving e-health technology. CONCLUSIONS: A generic structuring of the administration process and particular error-prone sub-steps may facilitate the allocation of prevention strategies and help to identify research gaps.

Difficulties swallowing solid oral dosage forms in a general practice population: prevalence, causes, and relationship to dosage forms.

PURPOSE: We assessed the prevalence of difficulties in swallowing solid oral dosage forms in a general practice population. Reasons, nature, and characteristics of tablets and capsules causing such difficulties were investigated as well as general practitioners' (GP) awareness of these difficulties. METHODS: A questionnaire survey was conducted in 11 general practices and consecutive patients taking at least one solid oral dosage form for ≥4 weeks were invited to respond to a questionnaire at the practices and one at home. Physicians completed a short questionnaire for each included patient. RESULTS: Of all participants (N = 1,051), 37.4 % reported having had difficulties in swallowing tablets and capsules. The majority (70.4 %) of these patients was not identified by their GP. The occurrence of swallowing difficulties was related to gender (f>m), age (young>old), dysphagia [adjusted odds ratio (adOR): 7.9; p < 0.0001] and mental illness (adOR: 1.8; p < 0.05). By asking "Do you choke while eating or drinking?", affected patients could be identified with a sensitivity of 62.6 % and a specificity of 78.1 %. Because of these difficulties, 58.8 % of the affected patients had already modified their drugs in a way that may alter safety and efficacy and 9.4 % indicated to be non-adherent. CONCLUSIONS: One in 11 primary care patients had frequent difficulties in swallowing tablets and capsules while GPs grossly underestimated these problems. Therefore, physicians should rule out swallowing difficulties regularly to avoid non-adherence and inappropriate drug modifications. Special attention should be paid to specific patient groups (e.g. women and patients with dysphagia, dysphagia indicators, or mental illness).
