Effect of complementary and alternative medicine during radiotherapy on radiation toxicity

Complementary and Alternative Medicine Attitudes of Gynecologic Patients: Experience in a Tertiary Clinic

OBJECTIVE

 To evaluate the knowledge, attitudes, and behaviors regarding complementary and alternative medicine methods of patients who were admitted to gynecology outpatient clinics.

METHODS

 In the present survey, a questionnaire on complementary and alternative medicine practices was applied on 1,000 women (ages between 18 and 83 years old) who were admitted to the gynecology outpatient clinic of a tertiary maternity hospital. Demographic features and knowledge, attitudes, and behaviors about these methods were inquired in face-to-face interviews.

RESULTS

 While 80.7% of the total participants thought that complementary and alternative medicine was beneficial, only 37.5% of them had used these methods previously. The rate of prior knowledge on this subject was of 59.7% and the source of information was physicians for 8.5% of the patients. However, 72.4% of all participants wanted to obtain information on these methods and 93.7% wanted to be informed by physicians. In the decision tree model, having knowledge about complementary and alternative medicine was the most effective factor determining its use (p < 0.001). Phytotherapy was found to be the most used method, with 91.4%. The most preferred plant was onion (18.9%), and the most common reasons for herbal use were stress (15.4%) and fatigue (15.2%).

CONCLUSION

 More than one-third of the patients who applied to the gynecology outpatient clinics used one of the complementary and alternative medicine methods at least once. As gynecologists and obstetricians, we need to be more knowledgeable about these methods to provide correct guidance to our patients for accessing accurate and effective information.

Do recent research studies validate the medicinal plants used in British Columbia, Canada for pet diseases and wild animals taken into temporary care?

ETHNOPHARMACOLOGICAL RELEVANCE

There are insufficient safe and effective treatments for chronic pain in pets. In cases such as osteoarthritis there is no commercially available cure and veterinarians use NSAIDs to manage pain. Pet owners may have to plan for a lifetime of plant-based treatment for the conditions that lead to chronic pain in pets. Phytopharmacotherapies have the advantage of being less toxic, cheap or free, readily available, are more likely to be safe for long-term use and have the potential to reset the immune system to normal functioning.

AIM OF THE STUDY

To examine the recently published medicinal plant research that matches unpublished data on ethnoveterinary medicines (EVM) used for pets in Canada (British Columbia) to see if the EVM data can provide a lead to the development of necessary drugs.

MATERIALS AND METHODS

In 2003 semi-structured interviews were conducted with 60 participants who were organic farmers or holisitic medicinal/veterinary practitioners obtained using a purposive sample. A draft manual prepared from the data was then evaluated by participants at a participatory workshop that discussed the plant-based treatments. A copy of the final version of the manual was given to all research participants. In 2018, the recently published research matching the EVM data was reviewed to see if the EVM practices could serve as a lead for further research.

RESULTS AND CONCLUSION

Medicinal plants are used to treat a range of conditions. The injuries treated in pets in British Columbia included abscesses (resulting from an initial injury), sprains and abrasions. Dogs were also treated with medicinal plants for rheumatoid arthritis, joint pain and articular cartilage injuries. More than 40 plants were used. Anal gland problems were treated with Allium sativum L., Aloe vera L., Calendula officinalis L., Plantago major L., Ulmus fulva Michx., Urtica dioica L. and Usnea longissima Ach. Arctium lappa, Hydrangea arborescens and Lactuca muralis were used for rheumatoid arthritis and joint pain in pets. Asthma was treated with: Linum usitatissimum L., Borago officinalis L., Verbascum thapsus L., Cucurbita pepo L., Lobelia inflata L., and Zingiber officinale Roscoe. Pets with heart problems were treated with Crataegus oxyacantha L., Cedronella canariensis (L.) Willd. ex Webb & Berth, Equisetum palustre L., Cypripedium calceolus L., Pinus ponderosa Douglas ex Lawson, Humulus lupulus L., Valeriana officinalis L., Lobelia inflata L., Stachys officinalis (L.) Trev., and Viscum album L. The following plants were used for epilepsy, motion sickness and anxiety- Avena sativa L., Valeriana officinalis, Lactuca muralis (L.) Fresen., Scutellaria lateriflora L., Satureja hortensis L., and Passiflora incarnata L. Plants used for cancer treatment included Phytolacca decandra, Ganoderma lucidum, Lentinula edodes, Rumex acetosella, Arctium lappa, Ulmus fulva, Rheum palmatum, Frangula purshiana, Zingiber officinale, Glycyrrhiza glabra, Ulmus fulva, Althea officinalis, Rheum palmatum, Rumex crispus and Plantago psyllium. Trifolium pratense was used for tumours in the prostate gland. Also used were Artemisia annua, Taraxacum officinale and Rumex crispus. This review of plants used in EVM was possible because phytotherapy research of the plants described in this paper has continued because few new pharmaceutical drugs have been developed for chronic pain and because treatments like glucocorticoid therapy do not heal. Phytotherapuetic products are also being investigated to address the overuse of antibiotics. There have also been recent studies conducted on plant-based functional foods and health supplements for pets, however there are still gaps in the knowledge base for the plants Stillingia sylvatica, Verbascum thapsus, Yucca schidigera and Iris versicolor and these need further investigation.

Adjunctive Chinese herbal medicine therapy for nasopharyngeal carcinoma: Clinical evidence and experimental validation

BACKGROUND

To investigate the benefits of adjunctive Chinese herbal medicine (CHM) for patients with nasopharyngeal carcinoma (NPC).

METHODS

We included all patients diagnosed with NPC during 1997-2009 and followed until 2011 in Taiwan. We used 1:1 frequency matching by age, sex, comorbidity, conventional treatment, and index year to compare the CHM users and non-CHM users (n = 2542 each). The prescribed CHM was further investigated with regard to its cytotoxicity.

RESULTS

Compared with non-CHM users, adjunctive CHM users had a lower hazard ratio of mortality risk, and a better survival probability. Gan-Lu-Yin (GLY) was the most commonly prescribed CHM, and it reduced cell viability, inhibited tumor proliferation, and induced apoptosis through the poly (ADP-ribose) polymerase and caspase-3-dependent pathway in human NPC TW01 cells. Oral administration of GLY retarded NPC-TW01 tumor growth in the xenograft nude mouse model.

CONCLUSION

Real-world data and laboratory experiments implied that adjunctive CHM might be beneficial for NPC patients.

Estudio cualitativo sobre los significados de la Medicina Complementaria y Alternativa para el cáncer en estudiantes de Ciencias de la Salud

Las representaciones sociales (RS) han sido desde siempre un concepto fundamental para la psicología (Moscovici, 1973). El presente estudio cualitativo utiliza el concepto de RS aplicado al campo de la Salud, con el objetivo de analizar las RS de la Medicina Complementaria y Alternativa (MCA) para el cáncer en estudiantes de Ciencias de la Salud, utilizando el análisis temático. Los resultados indican que las RS de la MCA se han elaborado con base en elementos muy diversos, pero donde prevale una objetivación y un anclaje de la MCA en lo que es común y familiar, más que en el conocimiento científico. Lo anterior para reflexionar sobre la formación de los futuros profesionales y sus prácticas en la cura del cáncer.

Complementary and alternative medicine use and disclosure amongst Australian radiotherapy patients

PURPOSE

Information on complementary and alternative medicine (CAM) use in Australian radiotherapy patients is sparse. This study investigated the type and prevalence of CAM amongst an Australian regional radiotherapy patient cohort and the disclosure of information to the consultant radiation oncologist.

METHODS

A single hardcopy questionnaire survey was provided to patients regarding the use of CAM and discussion with the treating medical practitioner. The National Centre for Complementary and Alternative Medicine (NCCAM) classification was used to group responses. The study was open for a period of 4 months, and all patients on treatment during this period were approached.

RESULTS

A total of 170 questionnaires were distributed to eligible patients, and 152 patients returned a completed questionnaire (89.4 % response rate). Sixty-nine of the 152 patients (45.4 %) reported active CAM use. Of the 69 patients who used CAM, mind-body medicine (n = 54, 78.3 %) and biological-based therapies (n = 54, 78.3 %) were the commonest NCCAM group, whilst manipulative/body-based therapies (n = 44, 63.8 %), whole medical systems (n = 7, 10.1 %) and energy therapies (n = 5, 7.2 %) were the least common. The most common therapies were vitamins and mineral supplementation (n = 33, 47.8 %) and massage therapy (n = 18, 26.1 %). Of note, only 29 participants stated that they had discussed CAM therapies with their radiation oncologist.

CONCLUSIONS

CAM use was prevalent amongst cancer patients undergoing radiotherapy, but frequently not discussed with the treating radiation oncologist. Considering the high prevalence of CAM, further resources could be justifiably directed at providing this service for cancer patients to foster a more holistic approach to their care.

Barriers to integration of traditional and complementary medicine in supportive cancer care of arab patients in northern Israel

In 2008, an Integrative Oncology Program (IOP), aiming to improve patients' quality of life during chemotherapy and advanced cancer, was launched within the Clalit Health Organization's oncology service at the Lin Medical Center, Haifa, Israel. The IOP clinical activity is documented using a research-based registry protocol. In this study, we present an analysis of the registry protocol of 15 Arab patients with cancer who were referred to the IOP. Analysis of patients' reported outcomes using the Edmonton Symptom Assessment Scale suggests that integrative medicine care improves fatigue (P = 0.024), nausea (P = 0.043), depression (P = 0.012), anxiety (P = 0.044), appetite (P = 0.012), and general well-being (P = 0.031). Barriers to integration of traditional and complementary medicine in supportive care of Arab patients are discussed followed by six practical recommendations aimed at improving accessibility of patients to integrative supportive care, as well as compliance with treatments.

Beliefs of New Zealand doctors about integrative medicine for cancer treatment

AIMS. This study aimed to give an up-to-date description of the views and knowledge that health professionals in New Zealand (NZ) have about complementary and alternative medicine (CAM) and its use in the context of integrative medicine.

STUDY DESIGN

A self-administered questionnaire.

METHODS

Doctors in the Otago region of New Zealand (n = 235 out of 395, 59% response rate) answered questions addressing attitudes toward the principle of integrative medicine, attitudes indigenous Ma-ori holistic views of health, and attitudes about CAM. Information on physician demographics was also gathered.

RESULTS

Almost all doctors (95%) agreed that they should address all aspects of a patient's health, whereas around 60% agreed that CAM can be integrated into a treatment regime to provide the best care for a patient. Most (93%) agreed that in a NZ context, it is important to be aware of Ma-ori holistic views of health. Doctors had many concerns about CAM, and only 26% personally used any CAM therapies themselves. However, many doctors wanted to learn more about CAM (58%) and Ma-ori holistic views of health (62%). Doctors who believed that they "knew enough" about CAM were more likely to ask about it and to recommend it to patients.

CONCLUSION

Integrative medicine is increasingly being accepted in medical practice, although many doctors still do not agree with the use of CAM. There is a need for increased patient-doctor discussions of CAM use. Doctors' lack of knowledge about CAM may be a barrier to communication and should be addressed with specific medical training.

Use of Chinese Medicine Among Survivors of Nasopharyngeal Carcinoma in Taiwan

Hypotheses. The authors hypothesized that the use of alternative medicine, in the form of Chinese medicine (CM), among patients in the continuing care phase of nasopharyngeal carcinoma (NPC) in Taiwan is higher than the use in a matched control group of noncancer individuals. Study design. This was a case-control study. Methods. Using a population-based claim database, the authors identified 181 long-term survivors of NPC and 905 matched controls. They obtained information on CM use and associated cost as outcome measures. Descriptive analysis and regression models were applied to examine the association between NPC and the outcome measures. Results. The unadjusted CM initiation (34% vs 32%; P = .54), intensity of use (2.15 vs 1.73 visits; P = .37), and cost (US$79 vs US$58; P = .16) were higher for patients in the NPC group than for those in the control group. Regression analyses suggested that the NPC group had significantly more CM visits (1.01; 95% confidence interval = 0.07-1.96), and more than 50% of these visits were related to cancer. Conclusion. The authors confirmed their hypotheses that the use of CM in the continuing care phase by patients with NPC in Taiwan was higher than the use in their matched, noncancer counterparts. These findings suggest that current clinical surveillance strategies for NPC might not meet patients’ physical and emotional needs.
