Disclosure of herbal medicine use to health care providers among pregnant women in Nepal: a cross-sectional study

Patient-physician communication on herbal medicine use during pregnancy: a systematic review and meta-analysis

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.

Assessing the safety and use of medicinal herbs during pregnancy: a cross-sectional study in São Paulo, Brazil

Background: Despite the lack of evidence supporting the safety and clinical efficacy of herbal medicine (HM), its use among pregnant women continues to increase. Given the high prevalence of contraindicated herbs among the pregnant population in Brazil, it is crucial to examine the use of HM and evaluate its safety based on the current scientific literature to ensure that women are using HM appropriately. Methods: A cross-sectional study was conducted from October 2022 to January 2023 at a public teaching hospital in São Paulo, Brazil. A total of 333 postpartum women in the postnatal wards and postnatal clinic were interviewed using a semi-structured questionnaire. The survey instrument consisted of 51 items covering the use of HM during pregnancy, sociodemographic and health-related characteristics, COVID-19 experiences, and pregnancy outcomes. For data analysis, chi-square and multivariate logistic regression were conducted using SPSS ver. 26.0. Results: Approximately 20% of respondents reported using HM during their most recent pregnancy, with a higher use observed among women from ethnic minority groups and those with prior HM experience. Among the 20 medicinal herbs identified, 40% were found to be contraindicated or recommended for use with caution during pregnancy. However, only half of the women discussed their HM use with obstetric care providers. Conclusion: This study emphasizes the continued public health concern regarding the use of contraindicated or potentially harmful HM among pregnant women in Brazil, highlighting the need for sustained efforts to reduce the risk of inappropriate HM use. By updating antenatal care guidelines based on the latest scientific evidence, healthcare providers can make informed clinical decisions and effectively monitor pregnant women's HM use, ultimately promoting safer and more effective healthcare practices.

Patterns and predictors of periodontal disease and tooth loss among users of smokeless tobacco

BACKGROUND

Smokeless tobacco (SLT) products of several different types are widely used in several South Asian countries including Pakistan. These products are consumed in different forms and with different names. The study aims to determine adverse effects of the SLT consumption on periodontal tissues.

METHODS

This cross sectional study was conducted in Karachi, Pakistan. It recruited 377 users of (SLT) with 231 males (61.3%) and 146 females (38.7%) of age 15 to 45 years. After obtaining informed consent, quantitative data were collected via a questionnaire followed by intra oral clinical examination to determine presence of periodontal diseases using community periodontal index (CPI). To determine the association between periodontal diseases and smokeless tobacco consumption habits, Chi Square test was conducted.

RESULTS

Gingival recession (Class II-IV) (65.8%) was the most prevalent periodontal disease among SLT users. CPI score was high (CPI score 3 and 4) in 31.3% participants, whereas tooth loss was found in 21%. Among types of SLT products, gutka (28.6%) and betel quid (23.3%) were most commonly used. Using SLT for five or more years was found to be associated with a high CPI score, gingival recession (Class II-IV), moderate to severe tooth mobility, and presence of tooth loss.

CONCLUSIONS

The study found statistically significant association between duration in years of using SLT and periodontal disease including gingival recession, tooth mobility and tooth loss. However, no significant results were found between retention during single use and frequency of SLT use per day. However, the link of these factors with the periodontal disease cannot be eliminated.

The use of Chinese herbal medicines throughout the pregnancy life course and their safety profiles: a population-based cohort study

BACKGROUND

Chinese herbal medicines have been long used among pregnant populations in China. However, despite the high susceptibility of this population to drug exposure, it continued to remain unclear about how often they were used, to what extent they were used at different pregnancy stages, and whether their use was based on sound safety profiles, particularly when used in combination with pharmaceutical drugs.

OBJECTIVE

This descriptive cohort study aimed to systematically investigate the use of Chinese herbal medicines throughout pregnancy and their safety profiles.

STUDY DESIGN

A large medication use cohort was developed by linking a population-based pregnancy registry and a population-based pharmacy database, which documented all prescriptions at both outpatients and inpatients from conception to 7 days after delivery, including pharmaceutical drugs and processed Chinese herbal medicine formulas that were approved by the regulatory authority and prepared under the guidance of national quality standards. The prevalence of the use of Chinese herbal medicine formulas, prescription pattern, and combination use of pharmaceutical drugs throughout pregnancy were investigated. Multivariable log-binomial regression was performed to assess temporal trends and further explore the potential characteristics associated with the use of Chinese herbal medicines. Of note, 2 authors independently conducted a qualitative systematic review of patient package inserts of the top 100 Chinese herbal medicine formulas used to identify their safety profiles.

RESULTS

This study included 199,710 pregnancies; of those pregnancies, 131,235 (65.71%) used Chinese herbal medicine formulas, including 26.13% during pregnancy (corresponding to 14.00%, 8.91%, and 8.26% in the first, second, and third trimesters of pregnancy) and 55.63% after delivery. The peak uses of Chinese herbal medicines occurred between 5 and 10 weeks of gestation. The use of Chinese herbal medicines significantly increased over the years (from 63.28% in 2014 to 69.59% in 2018; adjusted relative risk, 1.11; 95% confidence interval, 1.10-1.13), which was particularly great during pregnancy (from 18.47% in 2014 to 32.46% in 2018; adjusted relative risk, 1.84; 95% confidence interval, 1.77-1.90). Our study observed 291,836 prescriptions involving 469 Chinese herbal medicine formulas, and the top 100 most used Chinese herbal medicines accounted for 98.28% of the total prescriptions. Of those, a third (33.39%) were dispensed at outpatient visits; 6.79% were external use, and 0.29% were administered intravenously. However, Chinese herbal medicines were very often prescribed in combination with pharmaceutical drugs (94.96% overall), involving 1175 pharmaceutical drugs with 1,667,459 prescriptions. The median of pharmaceutical drugs prescribed in combination with Chinese herbal medicines per pregnancy was 10 (interquartile range, 5-18). The systematic review of drug patient package inserts found that the 100 most frequently prescribed Chinese herbal medicines contained a total of 240 herb constituents (median, 4.5); 7.00% were explicitly indicated for pregnancy or postpartum conditions; 43.00% were reported with efficacy or safety data from randomized controlled trials. Information was lacking about whether the medications had any reproductive toxicity, were excreted in human milk, or crossed the placenta.

CONCLUSION

The use of Chinese herbal medicines was prevalent throughout pregnancy and increased over the years. The use of Chinese herbal medicines peaked in the first trimester of pregnancy and was very often used in combination with pharmaceutical drugs. However, their safety profiles were mostly unclear or incomplete, suggesting a strong need for postapproval surveillance for the use of Chinese herbal medicines during pregnancy.

Reproducibility and Relative Validity of a Dietary Screener Adapted for Use among Pregnant Women in Dhulikhel, Nepal

OBJECTIVES

Here we examined the reproducibility and validity of a dietary screener which was translated and adapted to assess diet quality among pregnant Nepalese women.

METHODS

A pilot cohort of singleton pregnant women (N = 101; age 25.9 ± 4.1 years) was recruited from a tertiary, periurban hospital in Nepal. An adapted Nepali version of the PrimeScreen questionnaire, a brief 21-item dietary screener that assesses weekly consumption of 12 healthy and 9 unhealthy food groups, was administered twice, and a month apart, in both the 2nd and 3rd trimesters. Up to four inconsecutive 24-h dietary recalls (24-HDRs) were completed each trimester and utilized as the reference method for validation. For each trimester, data from multiple 24-HDRs were averaged across days, and items were grouped to match the classification and three weekly consumption categories (0-1, 2-3, or 4 + servings/week) of the 21 food groups represented on the PrimeScreen.

RESULTS

Gwet's agreement coefficients (AC1) were used to evaluate the reproducibility and validity of the adapted PrimeScreen against the 24-HDRs in both the 2nd and 3rd trimester. AC1 indicated good to excellent (≥ 0.6) reproducibility for the majority (85%) of food groups across trimesters. There was moderate to excellent validity (AC1 ≥ 0.4) for all food groups except for fruits and vegetables in the 2nd trimester, and green leafy vegetables and eggs in both the 2nd and 3rd trimesters.

CONCLUSIONS

The modified PrimeScreen questionnaire appears to be a reasonably valid and reliable instrument for assessing the dietary intake of most food groups among pregnant women in Nepal.

Mothers' Experiences of Childbirth and Perspectives on Korean Medicine-Based Postpartum Care in Korea: A Qualitative Study

This study aimed to record the experiences of childbirth and postpartum care of postpartum women and gain an in-depth understanding of their experiences of Korean medicine-based postpartum healthcare. The investigator conducted a 60–90-min interview with the 8 participants (mean age 34 years), and the comments were analyzed using the thematic analysis method. The two major themes emerging from the participants’ comments were: “experience and awareness of childbirth and postpartum care” and “experiences of the Korean medicine-based postpartum program”. The first theme was analyzed in four primary categories: (1) experiences of breakdown of the body and mind; (2) impossibility of postpartum care without help; (3) experiences of relentless effort for recovery; and (4) experiences of body and mind recovery. The second theme was analyzed in four primary categories: (1) participation with vague expectations; (2) experiences of the effects of managing postpartum symptoms; (3) the need for a comprehensive Korean medicine management for postpartum women; and (4) suggested improvements for the Korean medicine-based postpartum program. Mothers recognized the importance of Korean medicine treatment during the postpartum period for the management of Sanhupung symptoms and postpartum care and reported the benefits of body warming, Sanhupung prevention, pain reduction, and sense of psychological stability.
