Antibiotic-resistance in medically important bacteria isolated from commercial herbal medicines in Africa from 2000 to 2021: a systematic review and meta-analysis.

BACKGROUND: Antimicrobial resistance is swiftly increasing all over the world. In Africa, it manifests more in pathogenic bacteria in form of antibiotic resistance (ABR). On this continent, bacterial contamination of commonly used herbal medicine (HM) is on the increase, but information about antimicrobial resistance in these contaminants is limited due to fragmented studies. Here, we analyzed research that characterized ABR in pathogenic bacteria isolated from HM in Africa since 2000; to generate a comprehensive understanding of the drug-resistant bacterial contamination burden in this region. METHODS: The study was conducted according to standards of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). We searched for articles from 12 databases. These were: PubMed, Science Direct, Scifinder scholar, Google scholar, HerbMed, Medline, EMBASE, Cochrane Library, International Pharmaceutical Abstracts, Commonwealth Agricultural Bureau Abstracts, African Journal Online, and Biological Abstracts. Prevalence and ABR traits of bacterial isolates, Cochran's Q test, and the I2 statistic for heterogeneity were evaluated using MedCalcs software. A random-effects model was used to determine the pooled prevalence of ABR traits. The potential sources of heterogeneity were examined through sensitivity analysis, subgroup analysis, and meta-regression at a 95% level of significance. FINDINGS: Eighteen studies met our inclusion criteria. The pooled prevalence of bacterial resistance to at least one conventional drug was 86.51% (95% CI = 61.247-99.357%). The studies were highly heterogeneous (I2 = 99.17%; p < 0.0001), with no evidence of publication bias. The most prevalent multidrug-resistant species was Escherichia coli (24.0%). The most highly resisted drug was Ceftazidime with a pooled prevalence of 95.10% (95% CI = 78.51-99.87%), while the drug-class was 3rd generation cephalosporins; 91.64% (95% CI = 78.64-96.73%). None of the eligible studies tested isolates for Carbapenem resistance. Extended Spectrum ß-lactamase genes were detected in 89 (37.2%) isolates, mostly Salmonella spp., Proteus vulgaris, and K. pneumonia. Resistance plasmids were found in 6 (5.8%) isolates; the heaviest plasmid weighed 23,130 Kilobases, and Proteus vulgaris harbored the majority (n = 5; 83.3%). CONCLUSIONS: Herbal medicines in Africa harbor bacterial contaminants which are highly resistant to conventional medicines. This points to a potential treatment failure when these contaminants are involved in diseases causation. More research on this subject is recommended, to fill the evidence gaps and support the formation of collaborative quality control mechanisms for the herbal medicine industry in Africa.

Herbal medicines use and associated factors among pregnant women in Debre Tabor town, north West Ethiopia: a mixed method approach.

BACKGROUND: Use of herbal medicines during pregnancy has been increase in many developing and developed countries. In spite of the studies done on herbal medicine, no study has addressed use of herbal medicine among pregnant women in Debre Tabor Town. Hence, the major aim of this study was to assess the prevalence of herbal medicine use and associated factors. METHODS: A community based explanatory sequential mixed methods was employed. The quantitative method used cross-sectional study design with a sample size of 267 women, also 12 participants in a group for focus group discussion and 6 in-depth interviews from focus group were included for a qualitative part using a purposive sampling technique. The data were coded and entered into Epidata 4.2.0.0 and analysis was done using SPSS version 25, while thematic analysis was used for qualitative data. Bivariate and multivariate logistic analyses were used to assess associations between dependent and independent variables. RESULTS: Ninety-five (36.3%) of pregnant women used herbal medicine during pregnancy. Prior use of herbal medicine (AOR: 3.138; 95% CI: 1.375, 7.162), unable to read & write (AOR: 9.316; 95% CI: 2.339, 37.101), presence of health problems (AOR: 3.263; 95% CI: 1.502, 7.090), drug availability (AOR: 9.872; 95% CI: 4.322, 22.551) and distance to the health facilities (AOR 6.153; 95% CI 2.487, 15.226) were significantly associated with use of herbal medicine. Only 5(5.3%) of herbal medicine users disclosed their herbal medicine use to their healthcare providers. Zingiber officinale, Eucalyptus globulus, Rutachalepensis, Linumusitatissimum, and Moringa stenopetala were the most commonly used herbal medicines by pregnant women. CONCLUSIONS: The use of herbal medicine during pregnancy is a common practice and significantly associated with educational status, prior use of herbal medicine, presence of health problems, drug availability and distance to the health facilities. Since there was high prevalence and low disclosure rate of herbal medicine use, it should be ensured that physicians/midwives establish a good level of communication with pregnant women.

The use of complementary and alternative medicine among hypertensive and type 2 diabetic patients in Western Jamaica: A mixed methods study.

BACKGROUND: The simultaneous or intermittent use of alternative treatments and prescription medications for hypertension and type 2 diabetes mellitus can have adverse health effects. OBJECTIVES: To identify beliefs and practices associated with the use of alternative treatments for hypertension and type 2 diabetes mellitus among patients. METHODS: A mixed-methods study including an investigator-administered survey and focus group discussion sessions using convenience sampling was conducted among patients aged ≥18 years during May to August 2018. Descriptive statistics were used to describe and compare demographic characteristics among groups of survey participants using JMP Pro 14.0. Thematic analysis was conducted to analyze the qualitative data using NVivo. RESULTS: Most study participants (87-90%) were on prescription medication for their condition. Of survey participants, 69% reported taking their medication as prescribed and 70% felt that prescription medicine was controlling their condition. Almost all participants (98%) reported using alternative treatments, mainly herbal medications, and 73-80% felt that herbal medicines controlled their conditions. One-third believed that herbal medicines are the most effective form of treatment and should always be used instead of prescription medication. However, most participants (85%) did not believe that prescription and herbal treatments should be used simultaneously. Most (76-90%) did not discuss herbal treatments with their healthcare providers. Four themes emerged from the focus group sessions: 1) Simultaneous use of herbal and prescription medicine was perceived to be harmful, 2) Patients did not divulge their use of herbal medicine to healthcare providers, 3) Alternative medicines were perceived to be highly effective, and 4) Religiosity and family elders played key roles in herbal use. CONCLUSIONS: This study provides useful insights into perceptions and use of alternative treatments by patients that can be used by healthcare providers in developing appropriate interventions to encourage proper use of prescription medicines and alternative medicines resulting in improved management of these chronic diseases.

Highs, Lows, and Health Hazards of Herbology: A Review of Herbal Medications with Psychotropic Effects.

Mental health disorders, including depression, anxiety, and insomnia, are leading causes of hospitalization and disability for young and middle-aged adults. Approximately one-half of Americans will be diagnosed with a mental illness during their lifetime. Plants and roots have been used as medicinal agents since the beginning of recorded time. Complementary and alternative medicine or complementary integrative medicine use has been increasing throughout most socioeconomic classes, cultures, and age categories. This article reviews herbal and alternative therapies used to treat anxiety, depression, and insomnia. Indications for use, patient education, and possible interactions with conventional prescribed psychotropic medications are analyzed.

Evaluation of dietary supplement, functional food and herbal medicine use by dietitians during the COVID-19 pandemic.

OBJECTIVE: The current study was conducted to evaluate the dietary habits of the dietitians who had a leading role in this regard during the pandemic and their use of dietary supplements, functional food and herbal medicines. DESIGN: A cross-sectional study. An online questionnaire was used as a data collection tool to identify the participants' socio-demographic characteristics, health statuses and dietary habits and their use of dietary supplements, functional foods and herbal medicines. SETTING: Turkey. PARTICIPANTS: The study population was 550 dietitians. RESULTS: In the current study, the participants' average age was 30·6 ± 9·1 years, and most of them (88·2 %) were women. More than half of the participants (88·9 %) thought that adequate and balanced nutrition would positively affect the course of COVID-19. To avoid COVID-19, 94·5 % of the dietitians used dietary supplements, 46·1 % herbal medicines and 34·9 % functional foods during the pandemic. The most commonly used dietary supplement was fish oil (81·9 %), functional food was vegetables and fruits (80·5 %) and the herbal medicine was cinnamon (63·5 %). Women's consumption of functional foods was approximately twice higher compared with men (95 % Cl: 1·048, 4·165; P < 0·05). The findings showed that the longer the dietitians were in their careers, the more functional foods and herbal medicines they used. CONCLUSION: During the pandemic, dietitians' use of foods with protective effects against diseases increased depending on their academic knowledge and experience in nutrition. The findings obtained in the current study suggest that an expert's opinion should be obtained before using dietary supplements and herbal medicines.

Herbal Medicine for Idiopathic Central Precocious Puberty: A Systematic Review and Meta-Analysis.

Introduction: Herbal medicine (HM) is widely used in East Asia to treat idiopathic central precocious puberty (ICPP). However, no systematic reviews of the efficacy and safety of HM for treatment of ICPP have been reported. Thus, this systematic review assessed the efficacy and safety of HM for ICPP. Most available clinical trials that investigated HM for ICPP were included in this review. Methods and analysis: Eleven databases, including Asian databases, were searched from the date of inception until June 2018. We included randomized controlled trials (RCTs) that assessed HM for ICPP. Results: Nine RCTs including 650 participants with ICPP, were included in this review. As a result of meta-analysis, response rate of HM group was 1.14 times higher compared with control group, with moderate level of evidence. Also, serum estradiol (E2) level was significantly lower in HM group compared to control group with moderate level of evidence. Notably, serum luteinizing hormone (LH) level (IU/L) and E2 level were significantly lower in HM group than triptorelin injection group with moderate level of evidence. Bone age index and uterine volume were also significantly lower in HM group than control group with very low level of evidence. The incidence of adverse events was lower in the HM group than control group, but it was not statistically significant. Conclusions: According to the results of the meta-analysis, it seems that HM treatment has a significant effect on the treatment of ICPP and can effectively reduce serum LH, E2 level, and bone age. In particular, as gonadotropin-releasing hormone analog therapy has a negative effect on the growth rate and final height if bone age ≥13 years, this study suggests that HM treatment may be helpful. Additional higher quality RCTs are needed to demonstrate the efficacy and safety of HM for treatment of ICPP.

Herbal medicine use among patients with viral and non-viral Hepatitis in Uganda: prevalence, patterns and related factors.

BACKGROUND: There is some evidence that patients with liver diseases commonly use complementary and alternative therapies to address general and liver-disease specific health concerns. The purpose of this study was to assess and describe prevalence, patterns and related factors of herbal medicine use among adults diagnosed with viral and non-viral hepatitis in Kampala, Uganda. METHODS: A cross-sectional study was conducted on 310 adult patients attending the gastrointestinal clinic in Mulago hospital referral hospital in Kampala. Data on prevalence, types and reasons for herbal medicine use was collected using standardized questionnaires and focus group discussions. Modified Poisson regression analyses were used to examine factors related to use. RESULTS: Usage of various herbal remedies within 12 months prior to April 2018 was reported by 46.1% (143/310) of patients with 27.3% (39/143) of these reporting having used conventional and herbal therapies concurrently. Herbal remedies were used to treat various health conditions including hepatitis. Patients with hepatitis C virus infection (PRR = 1.16, p = 0.02) compared to those with hepatitis B virus infection, and those who believed that it was safe to use herbal and conventional therapies concurrently (PRR = 1.23, p = 0.008) had higher prevalence odds of herbal medicine use. Conversely, patients who had been newly diagnosed with hepatitis (PRR = 0.69, p = 0.03) compared to those who had been diagnosed more than one-year prior, had lower prevalence odds of herbal medicine use. Various types of local herbs were reported as most commonly used however most patients did not know the ingredients of commercially prepared herbal therapies. CONCLUSION: A high prevalence of herbal medicine use was found among newly-diagnosed patients and patients with hepatitis C more likely to use herbal remedies after adjusting for other factors. Usage was influenced by the belief that herbal medicine is safe and effective. Health workers need to consistently elicit information about herbal remedy use. Research is needed on benefits, adverse effects and outcomes in patients who use herbal remedies to treat primary liver diseases in order to facilitate evidence of efficacy and product safety.

Herbal medicine from the perspective of type II diabetic patients and physicians: what is the relationship?

BACKGROUND: Diabetes mellitus (DM) is a major public health problem and one of the most challenging diseases worldwide. According to the World Health Organization (WHO), the Kingdom of Saudi Arabia (KSA) has the second highest rate of diabetes in the Middle East and seventh highest globally. Some diabetic patients may prefer to use alternative approaches such as herbal remedies to control their blood glucose level and this study aims to assess the prevalence of herbal usage and to evaluate users' and doctors' knowledge, attitudes and beliefs about herbal medicine as well as the patient/doctor relationship in this regard. METHOD: A cross-sectional survey was conducted in several hospitals and medical centres in Makkah, KSA, between January and March 2019. Around 289 type II diabetic patients and 105 doctors were interviewed. RESULTS: We found that 68% of the participants were frequent consumers of herbal remedies, especially cinnamon, ginger and fenugreek. Patients' knowledge of herbal usage was mainly gleaned from family and friends as well as social media, and we found that many (71.4%) did not bother to consult or inform their doctors about their choice to self-medicate with herbs. Patients had no concerns regarding the efficacy and safety of herbal usage use in diabetes, as around half of the participants believe that herbal medicine is effective (54%) and safe (46%) for treating symptoms of diabetes. Two-thirds of the doctors (66%) routinely ask patients whether they use herbs for their condition. Although 25% of the doctors took a positive view of herbal medicine in relation to diabetes, others expressed concerns with the rise in herb use and want to see more attention paid to safety aspects. CONCLUSION: The study concludes that herbal remedies are commonly used by diabetic patients and that a gap exists in the relationship between patients and doctors concerning the disclosure of herbal remedy use and views on its safety.

Prevalence of complementary and alternative medicine (CAM) use in Brazil.

BACKGROUND: The use of medicinal plants or other alternative practices can be the only therapeutic resources for many communities and ethnic groups, especially in developing countries. In Brazil, the Ministry of Health incorporated Complementary and Alternative Medicine (CAM) as a public health policy since 2006. The aim of this study was to evaluate the prevalence of CAM use in Brazil. METHODS: This was a cross-sectional study performed as an epidemiological survey, with data from the National Health Survey, 2013 that evaluated a sample of adult Brazilians (18+ years old). The outcome was the use of CAM therapies, such as acupuncture, homeopathy, medicinal plants and herbal medicines in the last 12 months. We employed a logistic regression model (CI 95%) to evaluate the chances of CAM use. RESULTS: The prevalence of CAM use in Brazil was 4.5%. The subjects with higher chances to use CAM were: women (AOR = 1.42), aged > 40 years (AOR = 1.64), with higher educational levels (AOR = 2.35), and residents at North (AOR = 2.02) and South (AOR = 1.67) regions of Brazil, all with p-value < 0.001. According to the socioeconomic status, subjects from upper classes had higher chances to use acupuncture and homeopathy when compared to the other classes, and individuals from lower classes had higher chances to use medicinal plants and herbal medicines. Almost half of all individuals reporting CAM use did so outside the health care system. The Brazilian Unified Health System (SUS) was the least used funding for CAM when compared to other types of funding. CONCLUSIONS: We recommend that the Ministry of Health invests in capacity building for health professionals who work with CAM, providing structure for those practices in health services, increasing the access of CAM therapies for SUS users, and improving the registering of information about those therapies, encouraging the use of CAM by the Brazilian population.

Factors associated with local herb use during pregnancy and labor among women in Kigoma region, Tanzania, 2014-2016.

BACKGROUND: Despite research suggesting an association between certain herb use during pregnancy and delivery and postnatal complications, herbs are still commonly used among pregnant women in sub-Sahara Africa (SSA). This study examines the factors and characteristics of women using local herbs during pregnancy and/or labor, and the associations between local herb use and postnatal complications in Kigoma, Tanzania. METHODS: We analyzed data from the 2016 Kigoma Tanzania Reproductive Health Survey (RHS), a regionally representative, population-based survey of reproductive age women (15-49 years). We included information on each woman's most recent pregnancy resulting in a live birth during January 2014-September 2016. We calculated weighted prevalence estimates and used multivariable logistic regression to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for factors associated with use of local herbs during pregnancy and/or labor, as well as factors associated with postnatal complications. RESULTS: Of 3530 women, 10.9% (CI: 9.0-13.1) used local herbs during their last pregnancy and/or labor resulting in live birth. The most common reasons for taking local herbs included stomach pain (42.9%) and for the health of the child (25.5%). Adjusted odds of local herb use was higher for women reporting a home versus facility-based delivery (aOR: 1.6, CI: 1.1-2.2), having one versus three or more prior live births (aOR: 1.8, CI: 1.4-2.4), and having a household income in the lowest versus the highest wealth tercile (aOR: 1.4, CI: 1.1-1.9). Adjusted odds of postnatal complications were higher among women who used local herbs versus those who did not (aOR: 1.5, CI: 1.2-1.9), had four or more antenatal care visits versus fewer (aOR: 1.4, CI: 1.2-1.2), and were aged 25-34 (aOR: 1.1, CI: 1.0-1.3) and 35-49 (aOR: 1.3, CI: 1.0-1.6) versus < 25 years. CONCLUSIONS: About one in ten women in Kigoma used local herbs during their most recent pregnancy and/or labor and had a high risk of postnatal complications. Health providers may consider screening pregnant women for herb use during antenatal and delivery care as well as provide information about any known risks of complications from herb use.

Pharmaco-epidemiological research on herbal medicinal products in the paediatric population: data from the PhytoVIS study.

In paediatrics, clinical study data are limited, especially on herbal medicinal products. To address this gap, 2063 datasets from the paediatric population were evaluated in the PhytoVIS data base. By screening for paediatric data, information on indication, gender, treatment, co-medication and tolerability were evaluated. The majority of patients was treated because of common cold, fever, digestive complaints, skin diseases, sleep disturbances and anxiety. The perceived effect of the therapy was rated in 84% of the patients as very good or good without adverse events. The data shed light on a still neglected field of phyto-pharmacotherapy by giving information on the use of herbal medicines in an unselected cohort of paediatric patients. The results confirm the good clinical effects and safety of herbal medicinal products in this patient population and show that they are widely used in Germany.What is Known:• In Germany, about 85% of children receive one or more herbal medicinal products per year.• Despite international initiatives to promote clinical research in paediatrics, there are still many gaps of knowledge in the use of drugs in paediatrics.What is New:• The PhytoVIS project evaluated 2063 data sets from the paediatric population using herbal medicinal products.• The majority of patients was treated because of common cold, fever, digestive complaints, skin diseases, sleep disturbances and anxiety, and 84% of the patients rated the therapy as very good or good without adverse events.

The importance of herbal medicine use in the German health-care system: prevalence, usage pattern, and influencing factors.

BACKGROUND: Prevalence rates for herbal medicine (HM) have been increasing worldwide. However, little is known about prevalence, user characteristics, usage pattern and factors influencing HM usage for the general German population. METHODS: A nationwide online survey on HM usage was conducted in Germany. The 2906 participants were categorised into three groups: the ones who used HM in the last 12 months, the ones who did not use HM in the last 12 months but in their lifetime, and the ones who did not use HM until now. Data were analysed by descriptive statistics, Chi Square tests and binary hierarchical logistic regression analyses. RESULTS: Prevalence rates of HM were found to be very high for the general German population. Self-medication appeared as a common praxis, when at the same time HM users responded that they do not inform their physician about it, rate their knowledge about HM as somewhat poor, and use the internet as the most frequent source of information. The HM user in the last 12 months was found to include people that were more likely female, highly educated, privately insured, employed, and engaged in a more health-oriented lifestyle. While certain sociodemographic- and health-related variables influence HM usage vs. non-usage, they explain variance only to a limited extent. For distinguishing the user in the last 12 months vs. the less recent user who did not use HM in the last 12 months, ratings on different reasons for HM usage were found to perform better as predictors than sociodemographic- and health-related variables. CONCLUSIONS: This study demonstrated that HM usage plays an essential role in the German health-care system. Furthermore, the HM usage pattern may be potentially harmful for patients, as it included self-medication, little knowledge on interaction- and side-effects of HM, and a lack of communication with physicians about the usage. Moreover, prediction of HM usage in the previous year is impacted by variables beyond conventional sociodemographic- and health-related ones. In view of the high prevalence rates of HM in Germany, medical as well as health service providers should be aware of these issues.

Herbal or traditional medicine consumption in a Thai worker population: pattern of use and therapeutic control in chronic diseases.

BACKGROUND: Herbal and traditional medicines (HTM) are widely used in Asian countries. Specific data on prevalent of HTM usage and association with chronic diseases in the Thai population is currently lacking. We examined the prevalence and factors associated with HTM use in a Thai worker population. In addition, we explored the relationship between HTM use and therapeutic control of cardiovascular risk factors and documented the most common types of HTM used in various chronic diseases. METHODS: Employees of EGAT (The Electric Generating Authority of Thailand) who had participated in a health examination were studied. Each participant documented their HTM consumption and self-reported chronic diseases in a questionnaire. Clinical disease and therapeutic control were also defined by concomitant laboratory tests. RESULTS: Of a total of 6592 subjects, 32.6% were HTM-users. Age < 50 years, female gender, self-reported history of diabetes, liver disease, cancer, dyslipidemia, and alcohol use were independently associated with HTM use. HTM consumption increased in proportion to the numbers of self-reported chronic diseases. There were no differences in the therapeutic control of cardiovascular risk factors between HTM users and non-users. Liver and kidney function were not different. The most commonly used HTM was turmeric. CONCLUSIONS: HTM consumption is common in community-based Thai subjects, with higher use among those with chronic diseases. Although there were no differences in control of cardiovascular risk factors between HTM users and non-users, many of the commonly used herbs have relevant biological activities for chronic disease prevention or treatment.

Prevalence and predictors of chronic kidney disease among Ghanaian patients with hypertension and diabetes mellitus: A multicenter cross-sectional study.

The burden of chronic kidney disease (CKD) is rapidly rising in developing countries due to astronomical increases in key risk factors including hypertension and diabetes. We sought to assess the burden and predictors of CKD among Ghanaians with hypertension and/or diabetes mellitus in a multicenter hospital-based study. We conducted a cross-sectional study in the Ghana Access and Affordability Program (GAAP) involving adults with hypertension only (HPT), hypertension with diabetes mellitus (HPT + DM), and diabetes mellitus only (DM) in 5 health facilities in Ghana. A structured questionnaire was administered to collect data on demographic variables, medical history, and clinical examination. Serum creatinine and proteinuria were measured, and estimated glomerular filtration rate derived using the CKD-EPI formula. A multivariable logistic regression model was used to identify factors associated with CKD. A total of 2781 (84.4%) of 3294 participants had serum creatinine and proteinuria data available for analysis. The prevalence of CKD was 242 (28.5%) among participants with both DM and HPT, 417 (26.3%) among participants with HPT, and 56 (16.1%) among those with DM alone. Predictors of CKD were increasing age aOR 1.26 (1.17-1.36), low educational level aOR 1.7 (1.23-2.35), duration of HPT OR, 1.02 (1.01-1.04), and use of herbal medications aOR 1.39 (1.10-1.75). Female gender was protective of CKD aOR 0.75 (0.62-0.92). Among patients with DM, increasing age and systolic blood pressure were associated with CKD. There is high prevalence of CKD among DM and hypertension patients in Ghana. Optimizing blood pressure control and limiting the use of herbal preparations may mitigate CKD occurrence in high cardiovascular risk populations in developing countries.

What motivates new, established and long-term users of herbal medicine: is there more than push and pull?

BACKGROUND: The use of herbal medicine (HM) has become an essential form of treatment and it is more and more common around the world. Little is known about the reasons that drive people to initially use HM or to maintain their behaviour, and whether the so-called "push and pull factors" known in the context of decision making for complementary and alternative medicine, also play a role for HM use. Here, our goal was to provide answers to these open questions and to analyse the reasons that motivate new, established and long-term HM consumers in detail. METHODS: Thirteen reasons for HM usage, which were previously identified within a qualitative approach, were analysed quantitatively in a nationwide online survey in Germany. Data of 2,192 German HM users from the general population were grouped into new, established and long-term users. We performed a factor analysis in order to identify factors underlying the set of reasons. RESULTS: We discovered a reliable factor associated with longstanding family traditions and cultural importance of HM in Germany. This finding shows that the reasons for HM use require a three-factor structure going beyond the well-known push and pull factors that explain the use of complementary and alternative medicine. In using the identified factors for further calculations, we were able to reveal important group differences and test how the factor scores perform as predictors for the new, established and long-term choice of HM. Our results showed that a high score on the push factor is associated more with initial HM usage, while long-term HM usage is impacted more by high scores on the pull and traditional factors. CONCLUSIONS: Our exploratory survey and analysis of the reasons that underlie HM usage aimed at providing a better understanding of the decision for this treatment form. The findings of our work deliver insights for medical practitioners and health-care providers, including the role of family traditions for HM usage and the finding that new HM users are driven to use this treatment form in part because of negative aspects they associate with conventional medicine.

Improving rating scales: Applying Rasch analysis to student pharmacists' attitudes towards herbal medications.

BACKGROUND: This study analyzed the psychometric properties of a cross-sectional survey of student pharmacists' attitudes regarding herbal medications using a polytomous Rasch model. Seven items assessed students' attitudes towards herbal medications using a 6-point agreement scale (0 to 5). Student responses were reviewed to identify outliers and aberrant response patterns, assess scale fit, and perform item analysis. Scale performance was assessed to determine if response categories were independent and equally represented. Items were reviewed for model fit and construct validity with significant item gaps identified using a z-test. IMPACT: A total of 324 students completed the survey. The initial 6-point scale was analyzed. Student responses with outfit mean-square (MNSQ) values >5 were removed, yet the scale did not have appropriate functionality. The categories were merged to form a 4-point scale with no improvement. Therefore, two different 3-point scale options were analyzed: response categories of 0, 1 to 3, and 4 to 5; and response categories of 0, 1 to 4, and 5. With ten students removed, both 3-point scales met the requirements for functionality and all items exhibited good fit with MNSQ values between 0.6 and 1.4, person-separation value of 1.29, and person-reliability value of 0.62. RECOMMENDATIONS: Both 3-point scales met the requirements for Rasch analysis. The most optimal scale was the 0, 1 to 4, and 5 option. DISCUSSION: This study provides findings from the survey validity assessment alongside the survey results, which is useful for readers to have confidence in the quality of the study findings.

Use of herbal medicines: Pilot survey of UK users' views.

Increasing sales of medicinal plants as supplements or health foods continue to indicate widespread self-medication. We conducted a survey on users' views on obtaining information on herbal medicines and their experiences and opinions about their use. Responses over one-year period (01.08.2015-31.07.2016) were analysed. 157 participants took part (87% aged 45-64y, and 13% >65y). 80% participants used medicinal plants for multiple health benefits [i.e. health protection (74%), disease prevention (38%) and treatment (49%]). 95% believed in the medicinal powers of plants. Information regarding use of medicinal plants was predominantly based on books (57%), the internet (53%), friends, colleagues or neighbours (51%) and health practitioners (42%). 51% of participants felt herbs were safe (51%) with less side effects (55%) than pharmaceutical medicines. 24% of medicinal plant users informed their medical doctor, with majority of informed medical professional (47%) accepting the use of medicinal plants. This pilot survey provides new and valuable information for use in designing future more comprehensive surveys to provide essential information about the use of herbal medicines by the general population and health care providers' attitudes in the UK.

The prevalence and predictors of using herbal medicines among Iranian cancer patients.

BACKGROUND: and Purpose: Using of herbal medicines is common for cancer treatment. The aim of this study was to determine the prevalence, reasons, and predicting factors for the use of herbal medicines by Iranian cancer patients. MATERIALS AND METHODS: We conducted this cross-sectional study on 315 cancer patients through face-to-face interview in Kerman, Southeast of Iran, 2017. RESULTS: In total, 267 (84.1%) patients used at least one herbal medicine during chemotherapy courses, while only 42 (16.1%) patients discussed the use of herbal medicines with physicians. Living in urban regions (OR, 2.56; 95% CI, 1.30-5.05; P<0.0001) and the experience of constipation and diarrhea (OR, 2.11; 95% CI, 1.09-4.05; P = 0.02) were determined as some predicting factors for the use of herbal medicines. CONCLUSION: Our findings indicate that as herbal medicines are common among cancer patients and their use is often overlooked, physicians should pay particular attention to herbal medicines during chemotherapy.

Predicting the intention to use herbal medicines for anxiety symptoms: a model of health behaviour.

Background: Anxiety is a prevalent mental health condition in the Western world. Adults experiencing anxiety have been found to use a range of herbal medicines to manage anxiety symptoms.Aim: This study aimed to test a theoretical model based on the theory of planned behaviour that predicted the intention to use herbal medicines for anxiety symptoms, and to identify individual predictors of intention.Methods: An online survey was conducted with Australian adults who experienced anxiety and used herbal medicines (N = 400). A two-step approach to structural equation modelling was used to test a path model predicting the intention to use herbal medicines.Results: The model was found to be well-fitting. Attitude, subjective norms, control beliefs and severity of anxiety symptoms each significantly positively predicted intention to use herbal medicines for anxiety symptoms explaining 56% of the variance.Conclusions: The results suggest that mental health practitioners and policy makers need to ensure people experiencing anxiety have access to accurate and reliable information about herbal medicines to ensure they can effectively manage anxiety symptoms and safely engage in self-care.
