[Between chemotherapies, herbalism and spiritualities: Anthropological study of therapeutic pluralism in adults with cancer in Mexico]

OBJECTIVES

To analyze the characteristics of therapeutic pluralism in adult patients at a hospital Cancer Center, based on their health/illness/care-neglect trajectories.

METHODS

Analytical-explanatory, ethnographic, transversal-applied qualitative study. Data was provided by ten participants with cancer treated at the Veracruz State Cancer Center. Ethnographic records, participant observation and semi-structured interviews were carried out using observational guides, semi-structured interview guides and hospital clinical records. Participants were identified with pseudonyms for privacy and confidentiality.

RESULTS

Two main results were: 1) characterization of the diversity of therapies utilized by participants throughout their biographical trajectory related to their health/disease/care-neglect processes; 2) identification of the cultural characteristics involved in these complex processes of therapeutic plurality, closely related to the appearance of cancer.

CONCLUSION

Sociocultural aspects are interwoven with emerging therapeutic pluralities in the complex disease processes in cancer. The implications of these factors in the health/disease/care-neglect processes in cancer are manifest even before the first symptoms, in daily actions of self-care and preventive care. The mixing of therapies is an effect of the globalization characteristic of capitalist societies, in which therapeutic pluralism becomes an optimal phenomenon for commercialization and consumption.

Genoprotective activities of plant natural substances in cancer and chemopreventive strategies in the context of 3P medicine

Severe durable changes may occur to the DNA structure caused by exogenous and endogenous risk factors initiating the process of carcinogenesis. By evidence, a large portion of malignancies have been demonstrated as being preventable. Moreover, the targeted prevention of cancer onset is possible, due to unique properties of plant bioactive compounds. Although genoprotective effects of phytochemicals have been well documented, there is an evident lack of articles which would systematically present the spectrum of anticancer effects by phytochemicals, plant extracts, and plant-derived diet applicable to stratified patient groups at the level of targeted primary (cancer development) and secondary (cancer progression and metastatic disease) prevention. Consequently, clinical implementation of knowledge accumulated in the area is still highly restricted. To stimulate coherent co-development of the dedicated plant bioactive compound investigation on one hand and comprehensive cancer preventive strategies on the other hand, the current paper highlights and deeply analyses relevant evidence available in the area. Key molecular mechanisms are presented to detail genoprotective and anticancer activities of plants and phytochemicals. Clinical implementation is discussed. Based on the presented evidence, advanced chemopreventive strategies in the context of 3P medicine are considered.

Quality of life of Brazilian and Spanish cancer patients undergoing chemotherapy: an integrative literature review

OBJECTIVE

characterize the scientific production of Brazil and Spain in regard to methodological aspects and aspects of health-related quality of life experienced by cancer patients receiving chemotherapy in both countries.

METHOD

integrative literature review was conducted using the following databases: CINAHL, MEDLINE, SCOPUS and CUIDEN and the electronic libraries PubMed and SciELO, conducted in September 2013.

RESULTS

a total of 28 papers met the inclusion criteria. The synthesis of knowledge was presented in three categories of analysis: assessment of quality of life in different types of cancer; sociodemographic factors that influenced quality of life; and type of cancer and interventions that improve quality of life. Chemotherapy affects health-related quality of life and the most important factors were: age, sex, chemotherapy protocol, type of surgery, stage of the disease, educational level, and emotional intelligence. Complementary therapies such as acupuncture, guided visualization, prayers and exercise were positive and reduced side effects.

CONCLUSION

the results showed a poor level of evidence, since 86% of the studies were cross-sectional descriptive studies; the instrument most frequently used to measure health-related quality of life was EORTC QLQ C-30 and more studies were conducted in Brazil than in Spain.

Reiki for Cancer Patients Undergoing Chemotherapy in a Brazilian Hospital: A Pilot Study

The purpose of this pilot study was to explore whether individualized Reiki given to cancer patients at a Brazilian hospital improved symptoms and well-being. Data from 36 patients who received 5 Reiki sessions were collected using the MYMOP and were compared before and after their treatment and also with 14 patients who did not receive Reiki and who acted as a comparison group. Twenty-one patients reported feeling better, 12 felt worse, and 3 reported no change. Of the comparison group, 6 patients reported feeling better and 8 felt worse. The Reiki practice delivered as part of the integrative care in oncology did produce clinically significant effects, although not statistically significant results, for more than half of the patients undergoing cancer treatment.

Widespread use of complementary and alternative medicine among non-Hodgkin lymphoma survivors

There are few studies examining complementary and alternative medicine (CAM) use and beliefs among non-Hodgkin lymphoma (NHL) survivors. Seven hundred and nineteen patients with NHL from the University of Iowa/Mayo Clinic Molecular Epidemiology Resource who completed the 3-year post-diagnosis questionnaire were included in this study. Altogether 636 (89%) reported ever using CAM, with 78% utilizing vitamins, 54% alternative therapies and 45% herbals. Female gender was associated with increased overall CAM use (p=0.0001) as well as use of vitamins (p=0.0001), herbals (p=0.006) and alternative therapy (p=0.0002) for cancer. Older age (>60) was associated with increased vitamin use (p=0.005) and decreased herbal use (p=0.008). Among users, 143 (20%) believed CAM assists healing, 123 (17%) believed CAM relieves symptoms, 122 (17%) believed CAM gives a feeling of control, 110 (15%) believed CAM assists other treatments, 108 (15%) believed CAM boosts immunity, 26 (4%) believed CAM cures cancer and 36 (5%) believed CAM prevents the spread of cancer.

Pharmacopuncture for cancer care: a systematic review

Background. Pharmacopuncture, injection to acupoints with pharmacological medication or herbal medicine, is a new acupuncture therapy widely available in Korea and China for cancer-related symptoms. However, the evidence is yet to be clear. Objective. To determine pharmacopuncture's effectiveness on cancer-related symptoms. Methods. Eleven databases were searched for randomized controlled trials of pharmacopuncture in cancer patients. The Cochrane risk of bias (ROB) assessment tool was used for quality assessment. Results. Twenty-two studies involving 2,459 patients were included. Five trials of chemotherapy-induced nausea and vomiting (CINV) underwent meta-analysis. Pharmacopuncture significantly relieved severity of CINV compared with control group (3 trials, risk ratio (RR) 1.28, 95% confidence interval (CI) = 1.14-1.44). The frequency of CINV was also significantly reduced with pharmacopuncture (2 trials, RR 2.47, 95% CI = 2.12-2.89). Seventeen trials studied various symptoms, and in most studies, pharmacopuncture significantly relieved pain, ileus, hiccup, fever, and gastrointestinal symptoms and improved quality of life in various cancer patients. ROB was generally high. Conclusion. It may be suggested with caution that pharmacopuncture may help various symptom relief in cancer patients, but it is hard to draw a firm conclusion due to clinical heterogeneity and high ROB of the included studies, hence warranting further investigation.

Biologically based therapies are commonly self-prescribed by Brazilian women for the treatment of advanced breast cancer or its symptoms

PURPOSE

Breast cancer (BC) might be associated with loss of function in affected patients, with a direct impact on their quality of life (QOL). Many women with metastatic BC seek relief of symptoms, including the use of complementary and alternative medicine (CAM) to cure cancer. The present study aimed to identify the pattern of CAM used by patients with metastatic BC and to assess the correlation between CAM use and scores on anxiety, depression, and QOL scales.

METHODS

A total of 126 women with metastatic BC were interviewed using four instruments: (1) a questionnaire containing socioeconomic, clinical, and demographic data and CAM use; (2) European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ)-C30; (3) EORTC QLQ-BR23; and (4) the Hospital Anxiety and Depression Scale.

RESULTS

Fifty percent of the participants reported the use of at least one CAM modality. Biologically based practices were the most frequently used to treat BC and/or its symptoms, the most commonly discussed with the oncologists, and one of the CAM categories in which more patients reported a desire to learn more about. The overall use of CAM was not correlated with the scores on the anxiety, depression, and QOL scales. However, analysis of the association of the QOL scores with specific CAM modalities revealed some potential associations (especially for food supplements, art therapy, psychotherapy, and prayer).

CONCLUSIONS

Women with metastatic BC frequently make use of CAM to treat the cancer and/or its symptoms. Biologically based practices seem to be particularly important in Brazil. An association between specific CAM modalities and some QOL domains was suggested, but it needs further confirmation.

[Evidence-based practices published in Brazil: identification and analysis studies about human health prevention]

Integrative review of Brazilian studies about evidence-based practices (EBP) about prevention in human health, published in Web of Science/JCR journals, between October 2010 and April 2011. The aim was to identify the specialties that most accomplished these studies, their foci and methodological approaches. Based on inclusion criteria, 84 studies were selected, mainly published in public health journals, focusing on primary care and also addressing clinical issues and different specialties. Prevention foci and methodological approaches also varied, with a predominance of systematic reviews without meta-analysis. The results indicate that there is no single way to conceptualize and practice EBP in the field of prevention, and that its application may not only serve to obtain indisputable evidence to equip intervention actions. This endless knowledge area is under construction, with a view to the analysis and further understanding of health phenomena.

Percepções de coordenadores de unidades de saúde sobre a fitoterapia e outras práticas integrativas e complementares

As práticas integrativas e complementares estão em fase de expansão. O estudo objetivou conhecer o ambiente entre gestores para a inclusão de fitoterápicos na assistência. Nesta série de casos, descrevemos as percepções de coordenadores de unidades de saúde sobre as práticas integrativas. Os dados foram coletados em um questionário estruturado. O interesse pela inserção das terapias foi demonstrado por 13 dos 15 entrevistados, e o mesmo número relatou uso de fitoterapia. A fitoterapia também é indicada aos usuários por 13 dos coordenadores. O grupo percebe haver maior prescrição de plantas medicinais do que de fitoterápicos. Conclui-se que há boa perspectiva de aceitação da fitoterapia na rede.

Significado do cuidado familiar à mulher mastectomizada

Objetivou-se compreender o significado do cuidado familiar prestado à mulher mastectomizada. Estudo qualitativo, cujo referencial teórico utilizado foi o Interacionismo Simbólico, e o metodológico, a Teoria Fundamentada nos Dados. Entrevistaram-se 11 familiares entre julho e agosto de 2008. Os resultados evidenciaram os seguintes fenômenos: enfrentamento das dificuldades da família para cuidar, diagnóstico de câncer de mama defrontado pela família e cuidado familiar percebido após a cirurgia. Concluiuse que, apesar de os participantes valorizarem o cuidado familiar, alguns se sentiam despreparados para assumi-lo efetivamente. Considera-se a relação familiar consistente uma estratégia fundamental para a reabilitação da mulher mastectomizada.

[Evidence-based practices published in Brazil: identification and analysis of their types and methodological approches]

This is an integrative review of Brazilian studies on evidence-based practices (EBP) in health, published in ISI/JCR journals in the last 10 years. The aim was to identify the specialty areas that most accomplished these studies, their foci and methodological approaches. Based on inclusion criteria, 144 studies were selected. The results indicate that most EBP studies addressed childhood and adolescence, infectious diseases, psychiatrics/mental health and surgery. The predominant foci were prevention, treatment/rehabilitation, diagnosis and assessment. The most used methods were systematic review with or without meta-analysis, protocol review or synthesis of available evidence studies, and integrative review. A strong multiprofessional expansion of EBP is found in Brazil, contributing to the search for more selective practices by collecting, recognizing and critically analyzing the produced knowledge. The study also contributes to the analysis itself of ways to do research and new research possibilities.

Medicinas Alternativas e Complementares: uma metassíntese

O aumento do uso de Medicinas Alternativas e Complementares (MAC) motivou o crescimento do número de estudos qualitativos sobre o tema, justificando a realização de sínteses sobre esse material. Este artigo apresenta uma revisão sistemática de pesquisas qualitativas sobre MAC publicadas em periódicos internacionais. Esta revisão se orientou pela metodologia dos metaestudos. Foi realizada busca em revistas do Portal Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior e foram selecionados 32 artigos para análise. Os estudos revisados apresentam questões que têm como foco: o paciente, suas experiências terapêuticas e seus contextos sociais e culturais; o profissional, as relações profissionais e o processo de profissionalização das MAC; a MAC e sua relação com a biomedicina. Conclui-se que as pesquisas qualitativas sobre as MAC ensejam um olhar exploratório sobre o tema, procurando identificar as experiências de pacientes e profissionais com essas terapêuticas, assim como buscam discutir as conseqüências desse uso para a Medicina Convencional ou biomedicina.

Quality of sleep in postoperative surgical oncologic patients

This study aimed to evaluate surgical-oncologic patients' quality of sleep through the Pittsburgh Sleep Quality Index (PSQI) questionnaire. It is an exploratory study with transversal-observational design, in 46 postoperative head & neck and urology cancer patients. The PSQI questionnaire was used to evaluate the subjective quality of sleep and the occurrence of sleep disorders. Six PSQI components were statistically significant and 78.3% of the interviewees had impaired subjective quality of sleep. Among factors leading to sleep disorders we point out: taking too long to fall asleep; waking up in the middle of the night; getting up to go to the bathroom and napping during the day. This study is expected to sensitize the nursing team regarding the need to investigate quality of sleep and causes of its disorders in cancer survivors for an effective course of action.
