Defining and supporting a professional role for pharmacists associated with traditional and complementary medicines: a cross-country survey of pharmacists.

Introduction: An estimated 80% of the world's population use traditional and complementary medicine (T&CM) products as part of their healthcare, with many accessed through pharmacy. This cross-cultural study posed a set of professional practice responsibilities and actions to pharmacists related to T&CM products, with a view toward developing consensus, safeguarding, and promoting the health of the public. Methods: Data were collected from 2,810 pharmacists across nine countries during 2022 via a cross-sectional online survey reported in accordance with the guidelines of STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) and the Checklist for Reporting Results of Internet E-Surveys (CHERRIES). Results: Of the 2,810 participants from nine countries, 2,341 completed all sections of the survey. Of these, most agreed (69%) that T&CM product use was common in the community they served, but most did not have adequate training to support consumer needs. Over 75% acknowledged that there were known and unknown safety risks associated with T&CM use. Of 18 professional responsibilities posed, 92% agreed that pharmacists should be able to inform consumers about potential risks, including T&CM side effects and drug-herb interactions. The provision of accurate scientific information on the effectiveness of T&CM products, skills to guide consumers in making informed decisions, and communication with other healthcare professionals to support appropriate and safe T&CM product use were all ranked with high levels of agreement. In order to effectively fulfill these responsibilities, pharmacists agreed that regulatory reforms, development of T&CM education and training, and access to quality products supported by high-quality evidence were needed. Conclusion: General agreement from across nine countries on eighteen professional responsibilities and several stakeholder actions serve as a foundation for the discussion and development of international T&CM guidelines for pharmacists.

Prevalence and Characteristics of Australians Complementary Medicine Product Use, and Concurrent Use with Prescription and Over-the-Counter Medications-A Cross Sectional Study.

Data about the characteristics and prevalence of complementary medicine (CM) product use by Australians, including concurrent use with prescription and over-the-counter medications, have not been collected in the last five years. A cross-sectional online survey involving a representative sample of the Australian population was administered in 2021-2022. Of the 2351 survey responses included in this study, 49.4% reported use of a CM product over the previous 12-month period. Of these, 50% reported they always or often used CM products on the same day as a prescription medicine. Participants aged 65 and over were five times more likely to use CMs and other medications on the same day compared to 18-24-year-olds. Lower levels of education and having a chronic illness were also predictors of same-day use. The prevalence and characteristics of CM use by participants was similar to data collected five years ago. The study shows that concurrent use of CM products with prescription medications among older and more vulnerable populations is prevalent and this area requires further research to help ensure appropriate and safe use of CM products.

Interactions between natural products and cancer treatments: underlying mechanisms and clinical importance.

Natural products, also referred to as dietary supplements, complementary and alternative medicines, and health or food supplements are widely used by people living with cancer. These products are predominantly self-selected and taken concurrently with cancer treatments with the intention of improving quality of life, immune function and reducing cancer symptoms and treatment side effects. Concerns have been raised that concurrent use may lead to interactions resulting in adverse effects and unintended treatment outcomes. This review provides an overview of the mechanisms by which these interactions can occur and the current evidence about specific clinically important natural product-drug interactions. Clinical studies investigating pharmacokinetic interactions provide evidence that negative treatment outcomes may occur when Hypericum perforatum, Grapefruit, Schisandra sphenanthera, Curcuma longa or Hydrastis canadensis are taken concurrently with common cancer treatments. Conversely, pharmacodynamic interactions between Hangeshashinto (TJ-14) and some cancer treatments have been shown to reduce the side effects of diarrhoea and oral mucositis. In summary, research in this area is limited and requires further investigation.

A qualitative study of pharmacists' perceptions and awareness of homoeopathic medicines in Durban, South Africa.

BACKGROUND:  There is growing interest in the demand for and use of homoeopathic medicines by the public; however, little is known about the perspectives of pharmacists regarding the use of these medicines, particularly in the South African private health context. METHODS:  A qualitative approach using an exploratory cross-sectional descriptive design was used. Data were collected from a purposive sample of 15 participants comprising pharmacy managers, pharmacists and pharmacy assistants from six different conveniently selected private pharmacy retail outlets. Data were collected using individual interviews utilising a semi-structured interview guide. An audiotape was used to record the data which were transcribed verbatim and analysed thematically, following Tech's steps of data analysis. Ethical approval to conduct the study was obtained from the Durban University of Technology's Institutional Research Ethics Committee. RESULTS:  The findings of this study revealed four superordinate themes related to pharmacists' perceptions and self-reported awareness regarding homoeopathic medicines. These are (1) negative perceptions regarding homoeopathic medicines, (2) perceived benefits of homoeopathic medicines, (3) poor knowledge and awareness of homoeopathic medicines and (4) capacity development and curriculum aspects. CONCLUSION:  The findings highlight the need for an educational intervention on homoeopathic medicines targeting pre-service and in-service pharmacy practitioners, to enable them to provide effective education regarding all types of medicines as the demand for homoeopathic medicines increases.Contribution: The study findings provide evidence to support advocacy for an educational intervention to improve awareness and knowledge of pharmacists to enable provision of effective health education for patients. More research, however, is required to inform the contents of this training intervention for pharmacists.

Complementary medicines used in ulcerative colitis and unintended interactions with cytochrome P450-dependent drug-metabolizing enzymes.

BACKGROUND: Ulcerative colitis (UC) is an idiopathic, chronic inflammatory disease with multiple genetic and a variety of environmental risk factors. Although current drugs significantly aid in controlling the disease, many people have led to the application of complementary therapies due to the common belief that they are natural and safe, as well as due to the consideration of the side effect of current drugs. Curcumin, cannabinoids, wheatgrass, Boswellia, wormwood and Aloe vera are among the most commonly used complementary medicines in UC. However, these treatments may have adverse and toxic effects due to unintended interactions with drugs or drug-metabolizing enzymes such as cytochrome P450s; thus, being ignorant of these interactions might cause deleterious effects with severe consequences. In addition, the lack of complete and controlled long-term studies with the use of these complementary medicines regarding drug metabolism pose additional risk and unsafety. Thus, this review aims to give an overview of the potential interactions of drug-metabolizing enzymes with the complementary botanical medicines used in UC, drawing attention to possible adverse effects.

Psychosomatic Symptoms in Terminally Ill Cancer Patients and Its Relation With Using Complementary and Alternative Medicines: A Cross-Sectional Study in Southeast Iran.

Background: Cancer patients face various problems and complications, which they address through various complementary and alternative medicines (CAM). The aim of this study was to investigate the relationship between CAM and psychosomatic symptoms in terminally ill cancer patients. Methods: This cross-sectional study was performed on 221 terminally ill cancer patients (based on metastatic stage and according to the physicin diagnosis) in southeastern Iran. Convenience sampling was used to select terminally ill cancer patients. Using questionnaires like the demographic and clinical information questionnaire, Edmonton Symptom Assessment Scale (ESAS), Hospital Anxiety and Depression Scale (HADS), CAM questionnaire and satisfaction with the use of CAM, the researcher was able to compile a comprehensive picture of the population. Results: The mean age of the participants was 51.66 ± 13.34 years. The majority of the samples were female, married, educated, and unemployed. The mean score for the physical symptoms of the participants according to ESAS was 22.25 ± 17.57 which was less than the midpoint of the scale (the possible score of ESAS was 0-100). Only 2.7% (n = 6) and 0.9% (n = 2) of the participants had mild and moderate anxiety, respectively, and the other participants' anxiety levels were normal. Only 7.7% (n = 17) and 4.1% (n = 9) of the participants had mild and moderate depression, respectively, and the other participants' depression levels were normal. Last year, 87.3% of the participants used at least one type of CAM. Aside from prayer, 42.1% of the participants used at least one type of CAM in the last year. Prayer was used by 83.7% of the participants, medicinal plants by 35.8%, massage by 9.5%, dietary supplements by 3.6%, wet cupping by 3.2%, relaxation and meditation by 2.7%, dry cupping by 2.4%, and acupuncture by 0.5%. The common reason for using CAM was to reduce the stress and anxiety caused by cancer and to treat it. There were no significant differences in physical and psychological symptoms between the CAM-users and non-CAM users. Conclusion: Patients with cancer have a relatively low level of psychosomatic symptoms, and the primary reason for using CAM was to relieve stress and anxiety associated with cancer and treat it. However, psychosomatic symptoms were the same for CAM and non-CAM users. Because so many people with cancer use CAM, future studies should look into why and how CAM is used.

The prevalence of complementary and alternative medicines (CAM) usage among allergic rhinitis patients in Malaysia.

PURPOSE: We conducted this study to estimate the prevalence of complementary and alternative medicines (CAM) usage among allergic rhinitis (AR) patients in Malaysia and understand the practice of CAM usage among them. We also included a literature review on the commonly used CAM for AR. METHODS: A cross-sectional study which included a questionnaire-based study and information of allergic rhinitis from patient's clinic records. Patients with AR who attended the ORL-HNS department in Hospital Universiti Sains Malaysia and Hospital Sultanah Aminah, Malaysia were enrolled after consented, on a first-come first-serve basis as convenience sampling from July 2020 until February 2021. A pre-tested self-administered, 16-item questionnaire in Malay language was distributed to the participants. The questionnaire consists of a set of 16 questions with subsets to enquire about the sociodemographic data and pattern of usage of CAM and its effectiveness. RESULTS: 372 patients were enrolled in this study consisting of 217 (58.3%) female and 155 (41.7%) male patients. 231 (62.1%) participants had used CAM for AR in the past 10 years. A higher proportion of females (p = 0.015) and those with higher income (p = 0.004) had used CAM. Among the users, 87.9% found CAM to be effective. No differences were found in terms of age (p = 0.888) and education level (p = 0.057) for CAM usage. CONCLUSION: CAM is widely used in Malaysia to alleviate AR symptoms, with a large proportion of users think it is effective. Therefore, more researches should be conducted to provide evidence and guidance to integrate CAM into AR management.

The Australian obesity epidemic and the regulation of complementary medicine weight loss products.

OBJECTIVE: Investigate the response of the Therapeutic Goods Administration's (TGA) new advertising complaint system to resubmitted complaints about complementary medicine weight loss products previously upheld by the Complaint Resolution Panel. METHODS: Between July 2018 and July 2019, complaints about a convenience sample of 22 complementary medicines by eight sponsors, advertised on 140 different internet sites (cases), were resubmitted to the TGA. FatBlaster products featured. Follow-up occurred in February 2021. RESULTS: A search of the TGA advertising complaints database found 'no result' for 84% of the 140 cases submitted. Despite the TGA delisting three products and sponsors delisting ten others, all products complained about were still being advertised. Some products had minor changes in imagery but not claims. The sponsor (Cat Media, Naturopathica) had listed three new FatBlaster weight loss products. CONCLUSIONS: The TGA failed to protect consumers from ineffective weight loss medicines. Implications for public health: Weight loss medicines with misleading and deceptive claims are likely to divert users from evidence-based weight loss activities. The TGA should ask for the evidence supporting promotional claims for these products and, if this is lacking, delist the entire class of products. For recalcitrant sponsors who repeatedly make egregious claims, civil and criminal penalties should be applied.

The safety of commonly used vitamins and minerals.

Dietary supplements are the most common type of complementary medicine in Australia, reportedly used by 47% of the population. Vitamins and minerals are particularly popular Like all medicines, supplements can cause potential harms such as adverse reactions, drug interactions, monetary cost, delay of more effective therapy, false hope, and increased medication burden Although most vitamins and minerals are available for open sale, many are subject to legal restrictions as scheduled medicines, depending on the dose Consumers are at risk of overdose when the same ingredient is present in multiple products Health professionals can assist consumers by discussing the potential benefits and harms of vitamins and minerals and assisting them to find authoritative information Adverse events with vitamins and minerals should be reported to the Therapeutic Goods Administration.

Prevalence of drug-drug interactions in sarcoma patients: key role of the pharmacist integration for toxicity risk management.

BACKGROUND: The risk of drug-drug interactions (DDI) has become a major issue in cancer patients. However, data in sarcoma patients are scarce. We aimed to evaluate the frequency and the factors associated with DDI with antitumor treatments, and to evaluate the impact of a pharmacist evaluation before anticancer treatment. PATIENTS AND METHODS: We performed a retrospective review of consecutive sarcoma patients starting chemotherapy (CT) or Tyrosine kinase inhibitor (TKI). A pharmacist performed medication reconciliation and established an early toxicity risk assessment. Potential DDI with antitumor drugs were identified using Micromedex electronic software. RESULTS: One hundred and twenty-two soft-tissue and 80 bone sarcoma patients (103 males, median age 50 years,) were included before CT (86%) or TKI (14%). The median number of medications was 3; 34 patients (22% of patients with medication reconciliation) reported complementary medicine use. 37 potential DDI classified as major, were identified (12% of the 243 pre-therapeutic assessments). In multivariate analysis, TKI (p < 0.0001), proton pump inhibitor (p = 0.026) and antidepressant (p < 0.001) were identified as risk factors of DDI (p < 0.02). Only marital status (p = 0.003) was associated with complementary medicine use. A pharmacist performed 157 medication reconciliations and made 71 interventions among 59 patients (37%). In multivariate analysis, factors associated with pharmacist intervention were: complementary medicines (p = 0.004), drugs number (p = 0.005) and treatment with TKI (p = 0.0002) CONCLUSIONS: Clinical interventions on DDI are more frequently required among sarcoma patients treated with TKI than CT. Multidisciplinary risk assessment including a medication reconciliation by a pharmacist could be crucial to prevent DDI with TKI.

Self-medication with herbal medicine and breast cancer survival: a prospective monocentric study.

PURPOSE: The use of complementary and alternative medicine (CAM) is common among breast cancer patients, but less is known about whether CAM influences breast cancer survival. The primary aim of this study was to determine the impact of self-use of herbs on the overall survival. METHODS: This was a prospective study including 110 patients with breast cancer. All patients were questioned about the concept of taking herbs. We analyzed the demographic data and the overall survival. RESULTS: The average age was 51 years (30-80 years old). 37 had metastatic disease (33.6%). 48 patients had taken plants (43.6%). 19 patients consumed Graviola (39.6%) and 29 Alenda (60.4%). Overall survival at 3 years and at 5 years were, respectively, 96.2% and 82.4% in the absence of plant consumption versus 78.5% and 78.5% in case of plant consumption (p = 0.015). CONCLUSION: This study concluded that self-medication with Graviola or Alenda may be associated with an increase of death risk in patients with breast cancer. Further studies are needed to confirm these results.

Improving pharmacy practice in relation to complementary medicines: a qualitative study evaluating the acceptability and feasibility of a new ethical framework in Australia.

BACKGROUND: There is a need for clearer guidance for pharmacists regarding their responsibilities when selling complementary medicines. A recently published ethical framework provides guidance regarding the specific responsibilities that pharmacists need to meet in order to fulfil their professional obligations and make a positive contribution to health outcomes when selling complementary medicines. OBJECTIVE: Evaluate the acceptability and feasibility of a new ethical framework for the sale of complementary medicines in community pharmacy. METHODS: Australian community pharmacists were invited to participate in online focus groups and interviews. Participants were recruited via multiple methods, including social media and the professional networks of pharmacy groups. Participants were provided the ethical framework prior to the discussion. Discussions were transcribed verbatim and analysed using thematic analysis. RESULTS: Seventeen community pharmacists participated in the study (11 in 4 focus groups and 6 in individual interviews). There was good representation among participants in terms of gender, years of practice, pharmacy location and script volume. Participants differed in how proactive they were in relation to selling and providing advice on complementary medicines, how they interpreted evidence in relation to complementary medicines, and how they navigated their practice within the retail environment of community pharmacy. The majority of participants found the framework was acceptable for practice and was feasible for implementation with targeted support. Participants identified two important areas for targeted support in implementing the framework: improved access to evidence-based information resources on complementary medicines and independent evidence-based education and training on complementary medicine for pharmacists and pharmacy support staff. CONCLUSION: The ethical framework addresses an important gap in providing specific professional guidance to pharmacists when selling complementary medicines. The results of the study suggest that the framework may be acceptable to community pharmacists and be feasible to implement with targeted support.

An ethical framework for the responsibilities of pharmacists when selling complementary medicines.

BACKGROUND: Whether pharmacists should sell complementary medicines that lack evidence of effectiveness is an important ethical question which is not explicitly addressed in the existing literature or professional guidelines. The question arises because many complementary medicines lack rigorous evidence that they are effective. There is a need for specific practical guidance for pharmacists regarding their responsibilities when selling complementary medicines. OBJECTIVE: Outline and defend an ethical framework for the responsibilities of pharmacists when selling complementary medicines. METHOD: Principle-based ethics consists in the application of the four bioethical principles to make decisions in healthcare. A public health argument is provided that supports the sale of complementary medicines in pharmacy providing pharmacists meet a number of specific professional responsibilities. The theoretical resources provided by principle-based ethics are used to develop and defend a framework for the responsibilities of pharmacists when selling complementary medicines. The proposed framework is defended against counter-arguments that propose a stricter or more lenient approach. RESULTS: The framework identifies the following responsibilities of pharmacists selling complementary medicines: (1) pharmacists should provide evidence-based recommendations to consumers regarding complementary medicines, (2) pharmacists should train all staff in a pharmacy to ensure that they provide evidence-based recommendations regarding complementary medicines and refer to a pharmacist when required, (3) when providing advice, pharmacists should provide sufficient information for consumers to make informed decisions, (4) pharmacists should setup the pharmacy so that consumers are offered advice from a pharmacist when purchasing complementary medicines; pharmacists need to be available to provide that advice, and (5) pharmacists must be vigilant for complementary medicine harm and intervene if risk of harm is significant. CONCLUSION: The framework provides practical guidance for pharmacists regarding their responsibilities when selling complementary medicines.

Involving systems thinking and implementation science in pharmacists' emerging role to facilitate the safe and appropriate use of traditional and complementary medicines.

The use of traditional and complementary medicines (TM/CMs) has become an increasingly popular part of healthcare and self-care practices across the world. While the benefits and risks of many TM/CMs are yet to be fully evaluated, their prevalent use without consistent oversight has not been fully addressed by the public health sector. Pharmacists play an integral role in contributing to public health. Discussion about integrating TM/CMs into the professional practice of the pharmacist began over two decades ago. Nevertheless, TM/CMs are predominantly managed as "retail products" and are not integrated into pharmaceutical care and practice. While some isolated measures towards integration have been proposed, there remains no consensus on how to deliver pharmaceutical care in a coordinated, systematic manner. Systems thinking approaches are needed to formulate and implement strategies that change pharmacists' practice related to TM/CMs. Such approaches will ultimately reduce risk, optimize patient care, and result in better health outcomes.

Complementary and alternative medicine beliefs in type 2 diabetes: The Fremantle Diabetes Study Phase II.

Complementary medicine (CM) treatment beliefs of people with type 2 diabetes were assessed using a validated three-domain questionnaire. Belief in holistic health, but not natural treatments or participation in treatment, was independently associated with CM use (P = 0.003). Strong holistic health beliefs could identify present/future CM use, with potential management implications.

Impact of Up-Scheduling Medicines on Pharmacy Personnel, Using Codeine as an Example, with Possible Adaption to Complementary Medicines: A Scoping Review.

Within Australia, vitamins, minerals, nutritional supplements, essential oils, and homoeopathic and herbal preparations are collectively termed and regulated as Complementary Medicines (CMs) by the Australian Therapeutic Goods Administration (TGA). CMs are predominantly self-selected through a pharmacy, providing pharmacy personnel an opportunity to engage with the public about their CM use. CMs are currently non-scheduled products in Australia. This review aimed to summarize the literature reporting the potential effect on pharmacies if scheduling of CMs was adopted, using codeine as an example. A scoping review methodology was employed. Seven databases were searched to identify four key concepts, including: CMs, scheduling and rescheduling, codeine, and pharmacists. Seven studies were included for analysis. The majority of the literature has explored qualitative studies on the perception and opinion of pharmacists in relation to the up-scheduling of codeine. The case of codeine illustrates the possible impact of up-scheduling. If CMs were to be up-scheduled, the accessibility of CMs would be limited to the pharmacy providing a role for pharmacy personnel, including both pharmacists and pharmacy technicians, to counsel on CM use. However, careful collaboration and consideration on how such a regulatory change would impact other key-stakeholders, including CM practitioners, requires both a strategic and collaborative approach.

Resveratrol in Cancer Patients: From Bench to Bedside.

Resveratrol (3,5,4'-trihydroxystilbene) is a natural phytoalexin that accumulates in several vegetables and fruits like nuts, grapes, apples, red fruits, black olives, capers, red rice as well as red wines. Being both an extremely reactive molecule and capable to interact with cytoplasmic and nuclear proteins in human cells, resveratrol has been studied over the years as complementary and alternative medicine (CAM) for the therapy of cancer, metabolic and cardiovascular diseases like myocardial ischemia, myocarditis, cardiac hypertrophy and heart failure. This review will describe the main biological targets, cardiovascular outcomes, physico-chemical and pharmacokinetic properties of resveratrol in preclinical and clinical models implementing its potential use in cancer patients.

Use of biologically based complementary medicines in patients with neuroendocrine tumors.

Background: Biologically based complementary medicines (BB-CMs) are popular in patients with cancer. However, there are only limited data for BB-CMs in patients with neuroendocrine tumors (NET). We aimed to identify the prevalence and type of BB-CM use and the association to the nutritional risk score (NRS-2002) in NET patients. Methods: We performed a cross-sectional questionnaire study in NET outpatients at the Department of Hepatology and Gastroenterology at Aarhus University Hospital. The nutritional risk was determined by the NRS-2002. Results: We included 186 patients (51% women, median age 66 years). Sixty-six percent were regular BB-CM users. Forty-two percent used at least two supplements. The most popular BB-CMs were vitamin and mineral supplements (47%), calcium and vitamin D (34%). One-third used non-vitamin non-mineral supplements such as fish oil, herbs, Ginger, Q-10, garlic and probiotics. The use of BB-CMs was associated with female gender (48% vs. 37%, p < .05). Intake was significantly more frequent among patients with an NRS score ≥ 3, (60% vs. 76%) and in patients with change in performance status (58% vs. 76%), (p < .05, all). Patients reporting dietary changes used BB-CMs more frequently than patients without dietary changes (61% vs. 77%) (p < .05). Conclusions: In our study, 66% percent of NET patients use BB-CM and 42% used two or more supplements. Vitamins with and without herbal ingredients, minerals, calcium, vitamin D, and fish oil were the most popular supplements. The use of BB-CMs was associated with an NRS score ≥ 3, change in dietary intake, female gender, and change in ECOG performance status.

Yes to Recreational Drugs and Complementary Medicines But No to Life-Saving Medications: Beliefs Underpinning Treatment Decisions Among PLHIV.

Despite the life-preserving benefits of antiretroviral therapy (ART), some people living with HIV (PLHIV) delay, decline or diverge from recommended treatment while paradoxically being willing to use potentially dangerous substances, such as recreational drugs (RD) and complementary medicines (CM). During 2016 and 2017, interviews were conducted with 40 PLHIV, in Australia to understand drivers underpinning treatment decisions. While many believed ART to be effective, they expressed concerns about long-term effects, frustration over perceived lack of autonomy in treatment decisions and financial, emotional and physical burdens of HIV care. In contrast, they ascribed a sense of self-control over the use of RD and CM, along with multiple professed benefits. The perceived burden of ART emerged as a motivator for deviating from recommended treatment, while positive views towards RD and CM appear to justify use. This study may serve as guidance for the development of future strategies to address barriers to treatment uptake and adherence and subsequently health outcomes for PLHIV in Australia and elsewhere.

Use of traditional and complementary medicines by cancer patients at a national cancer referral facility in a low-income country.

OBJECTIVE: The aim of this study was to describe use of traditional and complementary medicines (T&CM) and associated factors among patients with cancer. METHODS: We conducted a cross-sectional study at the Uganda Cancer Institute (UCI) involving patients with selected solid tumours. Independent variables included age, sex, marital status, cancer site and stage. Main outcome variables were use and disclosure of use of T&CM. RESULTS: The majority of participants were women (n = 352; 81.9%). Breast cancer (n = 312; 71.9%) was the predominant cancer type. 55.4% of participants (n = 240) self-reported use of T&CM. Among them, 68.3% (140/205) reported using them to treat/cure cancer, 35.6% (72/202) for strengthening the immune system and 31.2% (63/202) for management of pain. Patients with advanced stage cancers were more likely to be users compared with those in stage one. The majority (81.9%, 195/238) of T&CM users did not disclose use to their healthcare professionals. The main reasons for nondisclosure included lack of inquiry by clinicians (79.6%, 117/147) and fear of disapproval and/or rebuke (11.6%, 17/147). CONCLUSION: Use of T&CM by patients with cancer under biomedical care is common but often undisclosed to the healthcare professionals.
