Complementary and Alternative Medicine (CAM) use by Malaysian oncology patients

A Cross-Sectional Assessment of Complementary and Alternative Medicine (CAM) Use among Patients with Chronic Diseases (CDs) in Qassim, Saudi Arabia

This study aims to investigate CAM use among CD patients from Qassim, Saudi Arabia and to compare CAM practice with different demographic and disease characteristics of the participants. A cross-sectional study was conducted among CD patients. During the three-months of data collection period, a total of 377 patients were approached and 208 patients participated in the study, giving a response rate of 55.17%. A p value of <0.05 was considered as significant. Among the study population, 94 (45.2%) patients were CAM users. Diabetes mellitus patients were the majority (48 (51.06%)) followed by hypertensive patients (34 (36.17%)). Spiritual therapies were the most common CAM followed by herbal products. Among CAM users, 41 (19.7%) patients reported disclosing CAM use to their health care providers. Among all the sociodemographic variables, gender (p = 0.029), marital status (p = 0.034) and education level (p = 0.047) were significantly associated with CAM use. In conclusion, the use of CAM among CD patients was relatively high in Qassim. Patients reported using CAM without disclosing to their health care providers which is a major health risk. It is critical to counsel CD patients regarding rational and informed CAM use in order to prevent harmful and unwanted effects.

Nasopharyngeal carcinoma among the Bidayuh of Sarawak, Malaysia: History and risk factors

Nasopharyngeal carcinoma (NPC) is a cancer of the epithelial cells lining the nasopharynx. The incidence of NPC has a distinct geographical distribution, mainly affecting the Chinese population of Southern China. In Malaysia, this cancer is exceptionally prevalent among males. There is a high incidence rate of NPC among the Bidayuh natives in Sarawak, Malaysia. Other than epidemiology reports, there has not been an article describing plausible cancer risk factors contributing to NPC within this native group. Researchers are still trying to understand the reasons the Bidayuh and Southern Chinese are highly susceptible to NPC. This article discusses the risk factors of developing NPC: Epstein-Barr virus infection, genetic predisposition, diet, environmental exposure and tobacco smoking. There is a need to improve the understanding of the role of risk factors to identify new ways to prevent cancer, especially among high-risk groups.

Use of complementary and alternative medicines (CAM) among Malaysian cancer patients for the management of chemotherapy related side effects (CRSE)

OBJECTIVES

Chemotherapy-related side effects (CRSE) are among the most distressing events cancer patients face. Some patients seek complementary and alternative medicines (CAM), increasing the risk of undesirable drug- CAM interactions. This study aims to identify the prevalence and type of CAM used for CRSE among cancer patients and patient's disclosure of CAM use to their prescribers.

METHODS

This was a questionnaire-based, cross-sectional study. Data was collected from cancer patients attending to three departments: surgical, medical and gynaecology at a local hospital in Malaysia. Ethical approval was obtained from the Medical Research Ethics Committee, Ministry of Health, Malaysia.

RESULTS

A total of 273 patients were recruited. Prevalence of CAM used for CRSE management was 166 (60.8%). Of the CAM users, 144 (86.7%) were female, 102 (61.4%) were employed and 123 (74.1%) were married. Breast cancer patients were found to be the highest users of CAM (n=76; 45.8%). The top three CAM used by patients in managing CRSE were dietary supplements (n=166; 100%); herbal products (n=154; 92.8%) and traditional Malay therapy (n=147; 88.6%). About 83% (n=137) patients disclosed CAM use to their prescribers. Among these, 58 (42.3%) reported that their doctors encouraged the use, whereas 89 (65.0%) patients claimed their doctors disagreed the use of CAM.

CONCLUSIONS

Prescribers still have doubt in combining chemotherapy with CAM, hence patients use CAM discreetly. Increasing the awareness and understanding of CAM use are mandatory to distinguish its possible synergistic or adverse reactions with cancer patients.

Potential factors that influence usage of complementary and alternative medicine worldwide: a systematic review

OBJECTIVES

To determine similarities and differences in the reasons for using or not using complementary and alternative medicine (CAM) amongst general and condition-specific populations, and amongst populations in each region of the globe.

METHODS

A literature search was performed on Pubmed, ScienceDirect and EMBASE.

KEYWORDS

'herbal medicine' OR 'herbal and dietary supplement' OR 'complementary and alternative medicine' AND 'reason' OR 'attitude'. Quantitative or qualitative original articles in English, published between 2003 and 2018 were reviewed. Conference proceedings, pilot studies, protocols, letters, and reviews were excluded. Papers were appraised using valid tools and a 'risk of bias' assessment was also performed. Thematic analysis was conducted. Reasons were coded in each paper, then codes were grouped into categories. If several categories reported similar reasons, these were combined into a theme. Themes were then analysed using χ2 tests to identify the main factors related to reasons for CAM usage.

RESULTS

231 publications were included. Reasons for CAM use amongst general and condition-specific populations were similar. The top three reasons for CAM use were: (1) having an expectation of benefits of CAM (84% of publications), (2) dissatisfaction with conventional medicine (37%) and (3) the perceived safety of CAM (37%). Internal health locus of control as an influencing factor was more likely to be reported in Western populations, whereas the social networks was a common factor amongst Asian populations (p < 0.05). Affordability, easy access to CAM and tradition were significant factors amongst African populations (p < 0.05). Negative attitudes towards CAM and satisfaction with conventional medicine (CM) were the main reasons for non-use (p < 0.05).

CONCLUSIONS

Dissatisfaction with CM and positive attitudes toward CAM, motivate people to use CAM. In contrast, satisfaction with CM and negative attitudes towards CAM are the main reasons for non-use.

Indicators for Medical Mistrust in Healthcare-A Review and Standpoint from Southeast Asia

The relationship based on trust is exceptionally important in healthcare, where life or death and quality of health are major concerns. Relational crack jeopardises the provision of quality healthcare when trust is taken for granted. Trust is believed to be the vital key to minimise medical negligence, lawsuits and patient complaints towards healthcare providers while acting as an empowering agent to significant clinical outcomes. Trust is indispensable to healthcare. However, to identify its deterioration is not a simple feature. Moreover, lack of research and public dissemination complicate this topic further. Hence, understanding medical mistrust issues and their associated indicators is urgently needed to ensure the top-notch provision of healthcare. We employed narrative review methodology together with key terms matching for the selected electronic databases for this article. Our review concluded that an "Increasing number of medical litigations and complaints towards physicians", "Physicians' low mastery of interpersonal communication skill" and "Patients' demand, practice, and non-disclosure of alternative treatments" are the possible indicators to predict mistrust. Efforts to restore and strengthen trust can only be made when these indicators are well understood firsthand.

Coping with future epidemics: Tai chi practice as an overcoming strategy used by survivors of severe acute respiratory syndrome (SARS) in post-SARS Hong Kong

BACKGROUND

Although SARS had been with a controversial topic for a decade at the time of this study, numerous SARS survivors had not yet physically, psychologically or socially recovered from the aftermath of SARS. Among chronically ill patients, the use of complementary and alternative medicine (CAM) is reported to be widespread. However, extremely little is known about the use of CAM by SARS survivors in the post-SARS period and even less is known about how the use of CAM is related to the unpleasant social and medical-treatment experiences of SARS survivors, their eagerness to re-establish social networks, and their awareness to prepare for future epidemics.

OBJECTIVE

To investigate the motivations for practising tai chi among SARS survivors in post-SARS Hong Kong.

DESIGN, SETTING AND PARTICIPANTS

Using a qualitative approach, I conducted individual semi-structured interviews with 35 SARS survivors, who were purposively sampled from a tai chi class of a SARS-patient self-help group in Hong Kong.

RESULTS

Health concerns and social experiences motivated the participants to practise tai chi in post-SARS Hong Kong. Experiencing health deterioration in relation to SARS-associated sequelae, coping with unpleasant experiences during follow-up biomedical treatments, a desire to regain an active role in recovery and rehabilitation, overcoming SARS-associated stigmas by establishing a new social network and preparing for potential future stigmatization and discrimination were the key motivators for them.

CONCLUSION

The participants practised tai chi not only because they sought to improve their health but also because it provided a crucial social function and meaning to them.

Quality of life-related outcomes from a patient-tailored integrative medicine program: experience of Russian-speaking patients with cancer in Israel

OBJECTIVE

Complementary/integrative medicine (CIM) is increasingly being integrated with standard supportive cancer care. The effects of CIM on quality of life (QOL) during chemotherapy need to be examined in varied socio-cultural settings. We purpose to explore the impact of CIM on QOL-related outcomes among Russian-speaking (RS) patients with cancer.

PATIENTS AND METHODS

RS patients undergoing chemotherapy receiving standard supportive care were eligible. Patients in the treatment arm were seen by an integrative physician (IP) and treated within a patient-tailored CIM program. Symptoms and QOL were assessed at baseline, at 6, and at 12 weeks with the Edmonton Symptom Assessment Scale (ESAS), the Measure Yourself Concerns and Wellbeing (MYCAW) questionnaire, and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30).

RESULTS

Of 70 patients referred to the treatment arm, 50 (71.4 %) underwent IP assessment and CIM treatments. Of 51 referred to the control arm, 38 (76 %) agreed to participate. At 6 weeks, CIM-treated patients reported improved ESAS scores for fatigue (P = 0.01), depression (P = 0.048), appetite (P = 0.008), sleep (P < 0.0001), and general wellbeing (P = 0.004). No improvement was observed among controls. Between-group analysis found CIM-treated patients had improved sleep scores on ESAS (P = 0.019) and EORTC (P = 0.007) at 6 weeks. Social functioning improved between 6 and 12 weeks (EORTC, P = 0.02), and global health status/QOL scale from baseline to 12 weeks (EORTC, P = 0.007).

CONCLUSION

A patient-tailored CIM treatment program may improve QOL-related outcomes among RS patients undergoing chemotherapy. Integrating CIM in conventional supportive care needs to address cross-cultural aspects of care.

Use of complementary and alternative medicines among Malaysian cancer patients: A descriptive study

The use of Complementary and Alternative Medicine (CAM; bǔ chōng yǔ tì dài yī xué) has been rapidly increasing among cancer patients. However, this pervasiveness is still largely unexplored among Malaysian cancer patients. The current study aimed to evaluate the patterns of CAM use among cancer patients from a local hospital in Malaysia. In addition, the study focused on the information-seeking behavior and CAM use disclosure to doctors. Of 393 patients, 184 (46.1%) had used CAM for their cancers. CAM usage was significantly associated with gender (p = 0.021), level of education (p = 0.001), employment status (p = 0.02), and monthly income (p < 0.001). Among frequently used CAM were nutritional supplements (n = 77, 41.8%), natural products (n = 74, 40.2%), and multivitamin (n = 62, 33.6%). Friends and family members were the most common source of CAM information (n = 139, 75.5%). Seventy-nine (43%) reported to disclose their CAM use to the health care providers. The most common (n = 63, 34.2%) reason of nondisclosure was "it is not important to discuss it with oncologist." This study confirmed that CAM use is common among Malaysian cancer patients, thus highlighting a greater need for patient education regarding CAM therapies and their potential interactions with conventional therapies. Although some types of CAM therapies may help patients to cope with emotional distress and improve quality of life, CAM, with no proven efficacy, may pose dangers to patients' health due to interactions with conventional therapies. Doctors and other health care providers including nurses and pharmacists should engage cancer patients in an open nonjudgmental dialog to ascertain CAM use disclosure to their health care providers.

Habb-e-Asgand, polyherbal Unani formulation, protects liver and antioxidative enzymes against paracetamol induced hepatotoxicity

Abstract Context: Habb-e-Asgand, a polyherbal Homeopathy/Unani drug from Hamdard Wakf Laboratory, India, used in arthritis, gout and joint pain, is a mixture of many herbal medicinal plants. Scientific attempts to test and validate its efficacy are meager. Objective: To evaluate the hepatoprotective and antioxidative potential of Habb-e-Asgand against paracetamol toxicity. Materials and methods: Swiss albino male mice (n = 5/group) were treated with Habb-e-Asgand (250 mg/kg, body weight (b.w.) in normal saline orally for 14 days followed by a single dose of paracetamol (400 mg/kg b.w./normal saline) intraperitoneally 24 h before euthanization. We estimated liver function (LFTs) using diagnostic kits, while antioxidant enzymes, cytochrome P450 (CYP) and lipid peroxidation (LPO) were measured using spectrophotometric methods. Results: Paracetamol alone induced LFTs enzymes significantly (p < 0.05 and p < 0.01, 0.001), serum glutamate pyruvate transaminase (SGPT, ∼70%), serum glutamate oxaloacetate transaminase (SGOT, ∼20%), alkaline phosphatase (ALP, ∼20%), total bilirubin (∼30%), CYP activity (∼50%) and LPO (∼45%), while it significantly inhibited the activity of antioxidant enzymes glutathione reductase (GR, ∼35%), glutathione peroxidase (GPx, ∼40%), glutathione S-tranferase (GST, ∼16%), catalase (CAT, ∼84%) and glutathione (GSH, ∼30%) contents. Habb-e-Asgand alone and in combination of paracetamol significantly (p < 0.05, 0.01, 0.001) decreased LFT levels (20-25%), CYP activity (∼45%) and LPO level (∼25%), while it induced antioxidant enzyme activity (GR, ∼15%; GPx, ∼17%; GST, ∼20% and CAT, ∼60%). Discussion: Paracetamol metabolites may be mediating production of reactive oxidant species (ROS) and liver injury, which are attenuated by Habb-e-Asgand antioxidant constituents. Conclusion: Habb-e-Asgand may be used as a prophylaxis for ROS related liver injury.

Complementary and alternative medicines (CAM) disclosure to the health care providers: a qualitative insight from Malaysian cancer patients

This study sought to evaluate Malaysian oncology patients CAM disclosure to the health care providers. Patients were interviewed across three major Malaysian ethnic groups, Malay, Chinese and Indian. Thematic content analysis identified three themes: reasons of CAM disclosure, reasons of CAM non-disclosure and preference of CAM discussion to health care providers. Patients agreed that CAM disclosure is important to avoid any interaction with the conventional medicines. Perceived lack of physicians' knowledge & interest in CAM, fear of termination of therapy by the physicians upon CAM disclosure, and perceived simplicity of some of the CAM therapies were among the reasons of non-disclosure. Given the option of oncologists, pharmacists or nurses, patients described oncologists as the most suitable person to discuss or disclose CAM use due to confidence in their clinical skills. Understanding the underlying beliefs of patients' reluctance to disclose CAM to health care providers is important especially when they are on an ongoing treatment for cancer.
