RESUMO
Background: The use of herbal medicines (HMs) for the treatment of hypertension (HTN) is increasing globally, but research on the potential adverse effects and safety of HMs in HTN patients is limited. Therefore, this systematic review and meta-analysis aim to determine the global prevalence of HM usage among HTN patients and assess the safety of identified herbs based on current scientific evidence. Methods: The PubMed/MEDLINE, EMBASE (Ovid), and Cumulated Index to Nursing and Allied Health Literature (CINAHL) databases were searched for cross-sectional studies on the use of HM among HTN patients. Our review includes studies published in English up to the year 2023. After extracting and appraising the data from the studies, a meta-analysis was conducted using the Stata version 16.0 to estimate the pooled prevalence of HM use in patients with HTN (PROSPERO: CRD42023405537). The safety classification of the identified HM was done based on the existing scientific literature. Results: This study analyzed 37 cross-sectional studies from 21 countries and found that 37.8% of HTN patients used HM to manage their health. The prevalence of HM use varied significantly based on publication year and geographical region. Among the 71 identified herbs, Allium sativum L., Hibiscus sabdariffa L., and Olea europaea L. were the most commonly used. However, four herbs were identified as contraindicated, 50 herbs required caution, and only 11 herbs were considered safe for use. Conclusion: The study highlights the potential risks of toxicities and adverse effects associated with HM use in the treatment of HTN. Ensuring patient safety involves using safe HMs in appropriate doses and avoiding contraindicated HMs. Future research should focus on identifying commonly used herbs, especially in resource-limited countries with poor HTN management, and additional clinical research is required to assess the toxicity and safety of commonly used HMs.
RESUMO
INTRODUCTION: Lack of transparent communication between patients and physicians regarding the use of herbal medicine (HM) presents a major public health challenge, as inappropriate HM use poses health risks. Considering the widespread use of HM and the risk of adverse events, it is crucial for pregnant women to openly discuss their HM use with healthcare providers. Therefore, this systematic review and meta-analysis aims to estimate the pooled prevalence of pregnant women's HM use and disclosure to healthcare providers and to examine the relationship between HM disclosure and various maternal and child health (MCH) measures. METHODS: A systematic search of five databases was conducted for cross-sectional studies on HM use during pregnancy published from 2000 to 2023. Data extraction followed a standardised approach, and Stata V.16.0 was used for data analysis. Also, Spearman's correlation coefficient was calculated to examine the association between use and disclosure of HM and various MCH indicators. RESULTS: This review included 111 studies across 51 countries on the use of HM among pregnant women. Our findings showed that 34.4% of women used HM during pregnancy, driven by the perception that HM is presumably safer and more natural than conventional medical therapies. However, only 27.9% of the HM users disclosed their use to healthcare providers because they considered HM as harmless and were not prompted by the healthcare providers to discuss their self-care practices. Furthermore, a significant correlation was observed between HM disclosure and improved MCH outcomes. CONCLUSION: Inadequate communication between pregnant women and physicians on HM use highlights a deficiency in the quality of care that may be associated with unfavourable maternal outcomes. Thus, physician engagement in effective and unbiased communication about HM during antenatal care, along with evidence-based guidance on HM use, can help mitigate the potential risks associated with inappropriate HM use.

BACKGROUND: Traditional and complementary medicine (T&CM) is commonly used in South Asian countries such as Nepal. There are various causes and contributing factors for patients with cancer to consider using T&CM. However, little is known about the use of T&CM among the cancer population in this region. METHODS: The study followed a cross-sectional design using a structured survey questionnaire. Survey participants were recruited from two National hospitals in Kathmandu, Nepal. The survey instrument comprised 30 questions, including variables on demographics, use of T&CM, and perceived level of disease severity, and cancer treatment. Chi-square test and logistic regression were used for data analysis using SPSS ver. 23.0. RESULTS: Of 908 participants, 31.6% used one or more modalities of T&CM after a cancer diagnosis. The most commonly used T&CM was Ayurveda (46.5%), followed by yoga (32.4%). About 46% of T&CM users discussed their use with their doctors. The main source of information on T&CM was their family members and relatives (55.7%). Cancer type (head and neck cancer OR: 2.30, CI: 1.23-4.29; abdominal cancer OR: 2.69, CI: 1.47-4.95; lung cancer OR: 5.88, CI: 2.69-12.89), cancer stage (Stage I OR: 1.92¸CI: 1.14-3.25; Stage II OR: 1.76, CI: 1.06-2.94), and the patients' self-rated disease severity (high perceived severity OR: 1.50, CI: 1.05-2.16) were strong predictors of T&CM use. CONCLUSION: This study underlined that despite the widespread use of T&CM among cancer patients in Nepal, most patients obtained information on T&CM from informal sources and did not disclose their use to physicians. To ensure the safe use of T&CM modalities, physicians should integrate questions on T&CM use into routine patient assessments in order to facilitate active communication and improve the quality of care.

Background: There are limited data on the use of herbal medicines (HM) among breastfeeding mothers, despite the fact that knowledge of the possible benefits or harms of HM use has a direct relationship with the health of infants, especially in resource-limited countries. The study aims to determine the prevalence and factors associated with HM use among breastfeeding mothers in Tanzania. Methods: The study followed a cross-sectional design using a structured survey questionnaire. Survey participants were recruited from the reproductive and child health clinic at Uhuru health center in Morogoro, Tanzania. The survey instrument comprised of 34 questions, including demographic information, the pattern of HM use during breastfeeding, and women's perceptions of HM. Chi-square test and logistic regression were used for data analysis using SPSS ver. 24.0. Results: The majority of the respondents (53.8%) used HM during breastfeeding. The most commonly used HM was black pepper (Piper nigrum L.; 80.0%), followed by pumpkin seeds (Cucurbita pepo L.; 18.0%). About one-third (27.5%) of HM users discussed their use with their healthcare providers. In addition, higher education levels and low breastmilk supply were identified as potential predictors of HM use. Conclusion: The practice of HM use among breastfeeding mothers in Tanzania is popular to ease breastfeeding difficulties. However, the issue of the safety or effectiveness of HM is still an unknown agenda. This awakens the need to evaluate HM's safety, efficacy, and quality through pharmacological studies for scientific evidence. Lastly, a clinical guideline should be developed in healthcare settings to promote open dialogues between the healthcare providers and mothers to ensure the safe use of HM.
RESUMO
BACKGROUND: The 2015 MERS outbreak in South Korea was the largest event outside of the Middle East. Under such circumstances, individuals tend to resort to non-conventional solutions such as complementary and alternative medicine (CAM) to manage health. Thus, this study aims to examine characteristics of CAM use among outpatients in a community hospital setting during the 2015 MERS outbreak and to assess potential predictors of CAM use during the epidemic. METHODS: A cross-sectional study was conducted among 331 patients (response rate: 82.75%) at a community hospital located in Seoul, South Korea. The survey instrument included 36 questions on the use of CAM, demographic characteristics, health status, and respondents' perceptions and concerns about MERS infection. Chi-square test and logistic regression were conducted for data analysis using SPSS ver. 21.0., and a p-value of less than 0.05 was considered statistically significant for all analyses. RESULTS: 76.1% of respondents used one or more types of CAM modalities during the MERS outbreak. Consumption of easily accessible modalities such as multivitamin (51.2%) and food products (32.1%) was most popular, and the majority of CAM users relied on mass media (52.4%) and the internet (27.4%) to obtain information on CAM. The use of CAM was associated with age between 40 and 49, age over 50, prior CAM use, and dissatisfaction with the government response to the MERS outbreak. CONCLUSIONS: CAM was commonly used by outpatients during the 2015 MERS outbreak in Korea, and mass media was the main source of information. Establishing a media platform is of paramount importance to provide reliable information and ensure the safety of its use.
