RESUMO

Online training may be a more effective and sustainable way to reach educators in early childcare centres (ECCs). This study compared the effectiveness of an online version of the Healthy Start-Départ Santé (HSDS) training to the traditional in-person version of the training as well as to the usual practice condition on ECC educators' healthy eating (HE) and physical activity (PA) practices and knowledge of PA and fundamental movement skills (FMS). Seventy-eight ECCs were randomly chosen across the provinces of New Brunswick and Saskatchewan, Canada and were allocated to either the online training, the in-person training or the usual practice groups between 2013 and 2018. Educators in each group completed a self-administered questionnaire before and nine months after the intervention, which included questions regarding their HE and PA practices in the ECC, as well as their knowledge of children's FMS and PA. Group differences were assessed with mixed-effect models. Compared to educators in the usual practice group, educators in the online training group reported a greater improvement in scores for HE and PA practices (p = 0.03 and 0.03, respectively), but change for educators in the in-person training group were not different (p = 0.8 and 0.56, respectively). The rate of improvement in FMS and PA knowledge did not differ across all three groups (p = 0.9). The HSDS online training is an effective method of improving educators' HE and PA practices in ECCs. Trial registration: ClinicalTrials.gov (NCT02375490).

RESUMO

BACKGROUND: Since young children spend approximately 30 h per week in early childcare centres (ECC), this setting is ideal to foster healthy behaviours. This study aimed to assess the effectiveness of the Healthy Start-Départ Santé (HSDS) randomized controlled trial in increasing physical activity (PA) levels and improving healthy eating and fundamental movement skills in preschoolers attending ECC. METHODS: Sixty-one ECC were randomly selected and allocated to either the usual practice (n = 30; n = 433 children) or intervention group (n = 31; n = 464 children). The HSDS intervention group was provided a 3-h on-site training for childcare educators which aimed to increase their knowledge and self-efficacy in promoting healthy eating, PA and development of fundamental movement skills in preschoolers. PA was measured during childcare hours for five consecutive days using the Actical accelerometer. Preschoolers' fundamental movement skills were assessed using the standard TGMD-II protocol and POMP scores. Food intake was evaluated using digital photography-assisted weighted plate waste at lunch, over two consecutive days. All data were collected prior to the HSDS intervention and again 9 months later. Mixed-effect models were used to analyse the effectiveness of the HSDS intervention on all outcome measures. RESULTS: Total number of children who provided valid data at baseline and endpoint for PA, food intake and fundamental movement skills were 259, 670 and 492, respectively. Children in the HSDS intervention group had, on average, a 3.33 greater point increase in their locomotor motor skills scores than children in the control group (ß = 3.33, p = 0.009). No significant differences in effects were observed for object control, PA and food intake. However, results demonstrated a marginal increase in portions of fruits and vegetables served in the intervention group compared to control group (ß = 0.06, p = 0.05). CONCLUSION: Of the 12 outcome variables investigated in this study, 10 were not different between the study groups and two of them (locomotor skills and vegetables and fruits servings) showed a significant improvement. This suggests that HSDS is an effective intervention for the promotion of some healthy behaviours among preschoolers attending ECC. TRIAL REGISTRATION: Clinical Trials NCT02375490.

RESUMO

BACKGROUND: Domains other than those commonly measured (physical, psychological, social, and sometimes existential/spiritual) are important to the quality of life of people with life-threatening illness. The McGill Quality of Life Questionnaire (MQOL) - Revised measures the four common domains. The aim of this study was to create a psychometrically sound instrument, MQOL - Expanded, to comprehensively measure quality of life by adding to MQOL-Revised the domains of cognition, healthcare, environment, (feeling like a) burden, and possibly, finance. METHODS: Confirmatory factor analyses were conducted on three datasets to ascertain whether seven new items belonged with existing MQOL-Revised domains, whether good model fit was obtained with their addition as five separate domains to MQOL-Revised, and whether a second-order factor representing overall quality of life was present. People with life-threatening illnesses (mainly cancer) or aged > 80 were recruited from 15 healthcare sites in seven Canadian provinces. Settings included: palliative home care and inpatient units; acute care units; oncology outpatient clinics. RESULTS: Good model fit was obtained when adding each of the five domains separately to MQOL-Revised and for the nine correlated domains. Fit was acceptable for a second-order factor model. The financial domain was removed because of low importance. The resulting MQOL-Expanded is a 21-item instrument with eight domains (fit of eight correlated domains: Comparative Fit Index = .96; Root Mean Square Error of Approximation = .033). CONCLUSIONS: MQOL-Expanded builds on MQOL-Revised to more comprehensively measure the quality of life of people with life-threatening illness. Our analyses provide validity evidence for the MQOL-Expanded domain and summary scores; the need for further validation research is discussed. Use of MQOL-Expanded will enable a more holistic understanding of the quality of life of people with a life-threatening illness and the impact of treatments and interventions upon it. It will allow for a better understanding of less commonly assessed but important life domains (cognition, healthcare, environment, feeling like a burden) and their relationship to the more commonly assessed domains (physical, psychological, social, existential/spiritual).

RESUMO

BACKGROUND: Prevention of childhood obesity is a key approach to the primary prevention of noncommunicable diseases. Several models, based on the population health approach and aligned with ecological models, are used to design childhood obesity prevention programs around the world. OBJECTIVE: This study aims to introduce the design and evaluation plan of "Iran Healthy Start (IHS)/Aghazi Salem, Koodake Irani"-the customized Iranian version of Canadian Healthy Start/Départ Santé health promotion program-which is now being developed in Mashhad University of Medical Sciences (Mashhad, Iran) and focuses on improving physical activity and healthy eating among preschool children. METHODS: We will evaluate the intervention using a pilot randomized controlled design. The components of intervention include customized Decoda Web-based resources for children, an implementation guide for educators and managers, training and monitoring, communication and knowledge exchange, building partnership, and parent engagement. Outcomes include changes in anthropometry, physical activity level, nutritional risk status and dietary intake, and quality of life. RESULTS: The project is funded by Mashhad University of Medical Sciences. The intervention was completed by the end of March 2018, and the analysis is currently under way. The first results of the IHS intervention program are expected to be submitted for publication in December 2018. CONCLUSIONS: The double burden of malnutrition in early years children is a major health concern in developing countries. This justifies the need for health promotion programs that are specifically designed to target both overnutrition and undernutrition prevention. If the efficacy approved, the IHS could potentially be a comprehensive health promotion program for young children whose lifestyle behaviors can be improved toward a healthy future life in a nutrition transition setting.

RESUMO

Stereotactic radiosurgery (SRS) has replaced whole brain radiotherapy (WBRT) as standard therapy for most patients with four or fewer brain metastases due to improved cognitive outcomes and more favorable health related quality of life (QoL). Whether SRS or WBRT is the optimal radiation modality for patients with five to fifteen brain metastases remains an open question. Efforts are underway to develop prospective evidence to answer this question. One of the planned trials is a Canadian Cancer Trials Group (CCTG)-lead North American intergroup trial. In general cancer treatments must have two basic aims: prolonging and improving QoL. In this vein, the selection of overall survival and QoL metrics as outcomes appear obvious. Potential secondary outcomes are numerous: patient/disease related, treatment related, economic, translational, imaging, and dosimetric. In designing a trial, one must also ponder what is standard WBRT-specifically, whether it should be associated with memantine. With the rapid accrual of an intergroup trial of hippocampal-sparing WBRT, we may find that the standard WBRT regimen changes in the course of planned trials. As up-front radiosurgery is increasingly used for more than 4 brain metastases without high level evidence, we have a window of opportunity to develop high quality evidence which will help guide our future clinical and policy decisions.

RESUMO

BACKGROUND: The Healthy Start-Départ Santé intervention was developed to promote physical activity, gross motor skills and healthy eating among preschoolers attending childcare centers. This process evaluation aimed to report the reach, effectiveness, adoption, implementation and maintenance of the Healthy Start-Départ Santé intervention. METHODS: The RE-AIM framework was used to guide this process evaluation. Data were collected across 140 childcare centers who received the Healthy Start-Départ Santé intervention in the provinces of Saskatchewan and New Brunswick, Canada. Quantitative data were collected through director questionnaires at 10 months and 2 years after the initial training and analyzed using descriptive statistics. Qualitative data were collected throughout the intervention. RESULTS: The intervention was successful in reaching a large number of childcare centres and engaging both rural and urban communities across Saskatchewan and New Brunswick. Centres reported increasing opportunities for physical activity and healthy eating, which were generally low-cost, easy and quick to implement. However, these changes were rarely transformed into formal written policies. A total of 87% of centers reported using the physical activity resource and 68% using the nutrition resource on a weekly basis. Implementation fidelity of the initial training was high. Of those centers who received the initial training, 75% participated in the mid-point booster session training. Two year post-implementation questionnaires indicated that 47% of centers were still using the Active Play Equipment kit, while 42% were still using the physical activity resource and 37% were still using the nutrition resource. Key challenges to implementation and sustainability identified during the evaluation were consistent among all of the REAIM elements. These challenges included lack of time, lack of support from childcare staff and low parental engagement. CONCLUSIONS: Findings from this study suggest the implementation of Healthy Start-Départ Santé may be improved further by addressing resistance to change and varied levels of engagement among childcare staff. In addition, further work is needed to provide parents with opportunities to engage in HSDS with their children.

RESUMO

INTRODUCTION: Childcare educators may be role models for healthy eating and physical activity (PA) behaviours among young children. This study aimed to identify which childcare educators' practices are associated with preschoolers' dietary intake and PA levels. METHODS: This cross-sectional analysis included 723 preschoolers from 50 randomly selected childcare centres in two Canadian provinces. All data were collected in the fall of 2013 and 2014 and analysed in the fall of 2015. PA was assessed using Actical accelerometers during childcare hours for 5 consecutive days. Children's dietary intake was measured at lunch on 2 consecutive days using weighed plate waste and digital photography. Childcare educators' nutrition practices (modelling, nutrition education, satiety recognition, verbal encouragement and not using food as rewards) and PA practices (informal and formal PA promotion) were assessed by direct observation over the course of 2 days, using the Nutrition and Physical Activity Self-Assessment for Child Care tool. Associations between educators' practices and preschoolers' PA and dietary intake were examined using multilevel linear regressions. RESULTS: Overall, modelling of healthy eating was positively associated with children's intake of sugar (ß=0.141, 95% CI 0.03 to 0.27), while calorie (ß=-0.456, 95% CI -1.46 to -0.02) and fibre intake (ß=-0.066, 95% CI -0.12 to -0.01) were negatively associated with providing nutrition education. Not using food as rewards was also negatively associated with fat intake (ß=-0.144, 95% CI -0.52 to -0.002). None of the educators' PA practices were associated with children's participation in PA. CONCLUSIONS: Modelling healthy eating, providing nutrition education and not using food as rewards are associated with children's dietary intake at lunch in childcare centres, highlighting the role that educators play in shaping preschoolers' eating behaviours. Although PA practices were not associated with children's PA levels, there is a need to reduce sedentary time in childcare centres.

RESUMO

Preschoolers observe and imitate the behaviors of those who are similar to them. Therefore, peers may be role models for preschoolers' dietary intake and physical activity in childcare centers. This study examined whether peers' behaviors predict change in preschoolers' dietary intake and physical activity in childcare centers over 9months. A total of 238 preschoolers (3 to 5years old) from 23 childcare centers in two Canadian provinces provided data at the beginning (October 2013 and 2014) and the end (June 2014 and 2015) of a 9-month period for this longitudinal study. Dietary intake was collected at lunch using weighed plate waste and digital photography on two consecutive weekdays. Physical activity was assessed using accelerometers over five days. Multilevel linear regressions were used to estimate the influence of peers' behaviors on preschoolers' change in dietary intake and physical activity over 9months. Results showed that preschoolers whose dietary intake or physical activity level deviated the most from those of their peers at the beginning of the year demonstrated greater change in their intakes and activity levels over 9months, which enabled them to become more similar to their peers (all ß 95% CI ranged from -0.835 to -0.074). This study suggests that preschoolers' dietary intake and physical activity may be influenced by the behaviors of their peers in childcare centers. Since peers could play an important role in promoting healthy eating behaviors and physical activity in childcare centers, future studies should test interventions based on positive role modeling by children.

RESUMO

BACKGROUND: Observational studies have suggested that patients with stage IV colorectal cancer who undergo surgical resection of the primary tumor (SRPT) have better survival. Yet the results are not confirmed in the setting of a randomized controlled trial. Lack of randomization and failure to control prognostic variables such as performance status are major critiques to the findings of the observational studies. We previously have shown that SRPT, independent of chemotherapy and performance status, improves survival of stage IV CRC patients. The current study aims to validate our findings in patients with stage IV CRC who were diagnosed during the period of modern chemotherapy. METHODS: A cohort of 569 patients with stage IV CRC diagnosed during 2006-2010 in the province of Saskatchewan was evaluated. Cox regression model was used for the adjustment of prognostic variables. RESULTS: Median age was 69 years (59-95) and M: F was 1.4:1. Fifty-seven percent received chemotherapy, 91.4% received FOLFIRI or FOLFOX & 67% received a biologic agent. Median overall survival (OS) of patients who underwent SRPT and received chemotherapy was 27 months compared with 14 months of the non-resection group (p<0.0001). Median OS of patients who received all active agents and had SRPT was 39 months (95%CI: 25.1-52.9). On multivariate analysis, SRPT, hazard ratio (HR):0.44 (95%CI: 0.35-0.56), use of chemotherapy, HR: 0.33 (95%CI: 0.26-0.43), metastasectomy, HR: 0.43 (95%CI: 0.31-0.58), second line therapy, HR: 0.50 (95%CI: 0.35-0.70), and third line therapy, HR: 0.58 (95%CI: 0.41-0.83) were correlated with superior survival. CONCLUSIONS: This study confirms our findings and supports a favorable association between SRPT and survival in patients with stage IV CRC who are treated with modern therapy.

RESUMO

BACKGROUND: Childhood obesity is a growing concern for public health. Given a majority of children in many countries spend approximately 30 h per week in early childcare centers, this environment represents a promising setting for implementing strategies to foster healthy behaviours for preventing and controlling childhood obesity. Healthy Start-Départ Santé was designed to promote physical activity, physical literacy, and healthy eating among preschoolers. The objectives of this study are to assess the effectiveness of the Healthy Start-Départ Santé intervention in improving physical activity levels, physical literacy, and healthy eating among preschoolers attending early childcare centers. METHODS/DESIGN: This study follows a cluster randomized controlled trial design in which the childcare centers are randomly assigned to receive the intervention or serve as usual care controls. The Healthy Start-Départ Santé intervention is comprised of interlinked components aiming to enable families and educators to integrate physical activity and healthy eating in the daily lives of young children by influencing factors at the intrapersonal, interpersonal, organizational, community, physical environment and policy levels. The intervention period, spanning 6-8 months, is preceded and followed by data collections. Participants are recruited from 61 childcare centers in two Canadian provinces, New Brunswick and Saskatchewan. Centers eligible for this study have to prepare and provide meals for lunch and have at least 20 children between the ages of 3 and 5. Centers are excluded if they have previously received a physical activity or nutrition promoting intervention. Eligible centers are stratified by province, geographical location (urban or rural) and language (English or French), then recruited and randomized using a one to one protocol for each stratum. Data collection is ongoing. The primary study outcomes are assessed using accelerometers (physical activity levels), the Test of Gross Motor Development-II (physical literacy), and digital photography-assisted weighted plate waste (food intake). DISCUSSION: The multifaceted approach of Healthy Start-Départ Santé positions it well to improve the physical literacy and both dietary and physical activity behaviors of children attending early childcare centers. The results of this study will be of relevance given the overwhelming prevalence of overweight and obesity in children worldwide. TRIAL REGISTRATION: NCT02375490 (ClinicalTrials.gov registry).

RESUMO

BACKGROUND: Although lymph nodes status and the ratio of metastatic to examined lymph node (LNR) are important prognostic factors in early-stage colorectal cancer (CRC), their significance in patients with metastatic disease remains unknown. The study aims to determine prognostic importance of nodal status and LNR in patients with stage IV CRC. METHODS: A cohort of 1109 eligible patients who were diagnosed with synchronous metastatic CRC in Saskatchewan during 1992-2010 and underwent primary tumor resection was evaluated. We conducted the Cox proportional multivariate analyses to determine the prognostic significance of nodal status and LNR. RESULTS: Median age was 70 years (22-98) and M:F was 1.2:1. Rectal cancer was found in 26 % of patients; 96 % had T3/T4 tumor, and 82 % had node positive disease. The median LNR was 0.36 (0-1.0). Fifty-four percent received chemotherapy. Median overall survival of patients who had LNR of <0.36 and received chemotherapy was 29.7 months (95 % CI 26.6-32.9) compared with 15.6 months (95 % CI 13.6-17.6) with LNR of ≥0.36 (P < .001). On multivariate analyses, no chemotherapy (HR 2.36 [2.0-2.79]), not having metastasectomy (HR 1.94 [1.63-2.32]), LNR ≥0.36 (HR 1.59 [1.38-1.84]). nodal status (HR 1.34 [1.14-1.59]), and T status (HR 1.23 [1.07-1.40]) were correlated with survival. Test for interaction was positive for LNR and high-grade cancer (HR 1.51 [1.10-2.10]). CONCLUSIONS: Our results suggest that nodal status and LNR are important prognostic factors independent of chemotherapy and metastasectomy in stage IV CRC patients.

RESUMO

OBJECTIVES: In order to improve healthy behaviours among rural children in their early years, a physical activity and healthy eating intervention (Healthy Start-Départ Santé) was implemented in rural childcare centres throughout Saskatchewan. The objective of the current study was to evaluate the impact of a multimodal physical activity and healthy eating intervention on educators' provision of opportunities for children to improve their physical activity levels, fundamental movement skills and healthy eating behaviours. SETTINGS: Six childcare centres (three Francophone and three Anglophone) located in five different rural and semi-rural communities in Saskatchewan participated in this intervention. PARTICIPANTS: A total of 69 children with a mean age of 4 years 9 months, and 19 female early childhood educators. INTERVENTION: Guided by an ecological framework, we implemented a population health controlled intervention, using a wait list control design (48 weeks delayed intervention), and evaluated its impact in rural childcare centres. Mixed methods were employed to determine the effectiveness of the intervention. OUTCOMES: Overall, educators felt that the intervention supported the provision of physical activity and healthy eating opportunities for children. Increases in children's physical activity levels were reported following the intervention. CONCLUSION: The lessons learned in this study can be used to improve the Healthy Start-Départ Santé intervention so that its implementation can be effectively expanded to childcare centres within and outside Saskatchewan, in turn, supporting the healthy development of early years (0-5) children in the province and beyond.

RESUMO

BACKGROUND: Surgical resection of the primary tumor in patients with stage IV colorectal cancer (CRC) remains controversial. Survival benefit reported in the literature has been attributed to the selection of younger and healthier patients with good performance status. We have recently reported that resection of the primary tumor improved survival of patients with stage IV CRC. In this study we examined survival benefit of surgery in patients with asymptomatic or minimally symptomatic primary tumor. PATIENTS AND METHODS: A cohort of patients with stage IV CRC and asymptomatic or minimally symptomatic primary tumor, who were diagnosed during the period of 1992 to 2005, in the province of Saskatchewan Canada, was evaluated. The Kaplan-Meier method was used to determine survival. A multivariate Cox proportional hazard regression analysis was performed to determine prognostic importance of resection of primary tumor. A test for interaction was performed for resection of primary tumor and other important clinicopathological variables. RESULTS: A total of 834 patients with a median age of 70 years (range, 22-93) and male:female ratio of 58:42 were identified. Among them 521 (63%) patients underwent surgery and 361 (43.3%) received chemotherapy. Patients who underwent surgery and received any chemotherapy had a median overall survival of 19.7 months (95% confidence interval [CI], 16.9-22.6) compared with 8.4 months (95% CI, 6.9-10.0) if they did not have surgery (P < .0001). In multivariate analysis, 5-fluorouracil-based chemotherapy (hazard ratio [HR], 0.43; 95% CI, 0.36-0.53), surgical resection of the primary tumor (HR, 0.47; 95% CI, 0.39-0.57), metastasectomy (HR, 0.48; 95% CI, 0.38-0.62), and second-line chemotherapy (HR, 0.72; 95% CI, 0.58-0.92) were correlated with superior survival. A test for interaction between ≥ 1 metastatic sites and surgery was significant, which suggests a larger benefit of surgery in patients with stage IVA disease. CONCLUSION: Results of this large population-based cohort study suggest that resection of the primary tumor in asymptomatic or minimally symptomatic patients with stage IV CRC improved survival independent of other prognostic variables. The benefit was more pronounced in stage IVA disease.

RESUMO

BACKGROUND: Chemotherapy improves survival in patients with stage IV colorectal cancer (CRC). Although in a clinical trial setting, strict eligibility criteria are used for chemotherapy, little is known about the use of chemotherapy in the general population. The study aims to assess clinicopathological variables that correlate with the use of chemotherapy in patients with stage IV CRC. METHODS: A retrospective cohort study involving patients with stage IV CRC, diagnosed between 1992 and 2005, in the province of Saskatchewan was carried out. A logistic regression analysis was performed to assess the correlation of various clinicopathological factors with the use of chemotherapy. RESULTS: A total of 1,237 eligible patients were identified. Their median age was 70 years (range: 22-98) and the male:female ratio was 1.3:1. 23.8% had an ECOG performance status (PS) of ≥2 and 61.8% of the patients had a comorbid illness. 46.8% of the patients received chemotherapy. The multivariate logistic regression analysis revealed that an age of <65 years [odds ratio (OR) 3.82, 95% CI: 2.59-5.63], metastasectomy (OR 3.60, 95% CI: 1.82-7.10), normal albumin (OR 3.26, 95% CI: 2.44-4.36), no comorbid illness (OR 2.87, 95% CI: 1.34-6.16), ECOG PS of <2 (OR 2.72, 95% CI: 1.94-3.82), normal blood urea nitrogen (OR 2.24, 95% CI: 1.40-3.59), palliative radiation (OR 2.03, 95% CI: 1.38-2.99), primary tumor resection (OR 2.00, 95% CI: 1.47-2.73), and the time period (OR 1.85, 95% CI: 1.41-2.42) were significantly correlated with the use of chemotherapy. CONCLUSIONS: The use of chemotherapy appears to be increasing in stage IV CRC. Patients treated with curative intention or who underwent primary tumor resection were more likely to receive chemotherapy. Despite a known benefit of chemotherapy in elderly patients, a differential use of chemotherapy was noted in this population.

RESUMO

BACKGROUND: Currently, there is very low-quality evidence available regarding benefit of surgical resection of the primary tumor (SRPT), in patients with stage IV colorectal cancer (CRC). In the absence of randomization, the reported benefit may reflect selection of younger and healthier patients with good performance status. A large population-based cohort study was undertaken to determine the survival benefit of SRPT in advanced CRC by eliminating various biases reported in the literature. METHODS: A retrospective cohort study involving patients with stage IV CRC, diagnosed between 1992 and 2005, in the province of Saskatchewan, Canada. Survival was estimated by using the Kaplan-Meier method. Survival distribution was compared by log-rank test. Cox proportional multivariate regression analysis was performed to determine survival benefit of SRPT by controlling other prognostic variables. RESULTS: A total of 1378 eligible patients were identified. Their median age was 70 years (range, 22-98 years) and male:female ratio was 1.3:1; 944 (68.5%) of them underwent SRPT. Among 1378 patients, 42.3% received chemotherapy and 19.1% received second-generation therapy. Patients who underwent SRPT and received chemotherapy had median overall survival of 18.3 months (95% confidence interval [CI] = 16.6-20 months) compared with 8.4 months (95% CI = 7.1-9.7 months) if they were treated with chemotherapy alone (P < .0001). Cox proportional analysis revealed that use of chemotherapy (hazard ratio [HR] = 0.47, 95% CI = 0.41-0.54), SRPT (HR = 0.49, 95% CI = 0.41-0.58), second-line chemotherapy (HR = 0.47, 95% CI = 0.45-0.64), and metastasectomy (HR = 0.54, 95% CI = 0.45-0.64) were correlated with superior survival. CONCLUSIONS: SRPT improves survival in patients with stage IV CRC, independent of other prognostic variables including age, performance status, comorbid illness and chemotherapy.

RESUMO

Background. Use of complementary and alternative medicine (CAM) by children with cancer is high; however, pediatric best cases are rare. Objectives. To investigate whether best cases exist in pediatric oncology using a three-phase approach and to compare our methods with other such programs. Methods. In phase I, Children's Oncology Group (COG) oncologists were approached via email and asked to recall patients who were (i) under 18 when diagnosed with cancer, (ii) diagnosed between 1990 and 2006, (iii) had unexpectedly positive clinical outcome, and (iv) reported using CAM during or after cancer treatment. Phase II involved partnering with CAM research networks; patients who were self-identified as best cases were asked to submit reports completed in conjunction with their oncologists. Phase III extended this partnership to 200 CAM associations and training organizations. Results. In phase I, ten cases from three COG sites were submitted, and most involved use of traditional Chinese medicine to improve quality of life. Phases II and III did not yield further cases. Conclusion. Identification of best cases has been suggested as an important step in guiding CAM research. The CARE Best Case Series Program had limited success in identifying pediatric cases despite the three approaches we used.

RESUMO

OBJECTIVE: To identify and evaluate surgical management of women with uterine fibroids. DESIGN: Retrospective analysis of mandatory surgical data sent to the Institute for Quality Assurance. SETTING: Data collection from 1998 to 2004 in Hesse, Germany. PATIENT(S): 34,814 women who underwent surgery for uterine fibroids. INTERVENTION(S): Patients were treated with either myomectomy or hysterectomy. MAIN OUTCOME MEASURE(S): Statistical analysis of mandatory surgical parameters. RESULT(S): Altogether, 4975 (14.3%) women had myomectomies, and 29,839 (85.7%) had hysterectomies. Age was an important determinant of surgical procedure; hysterectomy was preferred for patients over 40 (odds ratio 4.3; 95% confidence interval: 4.1-4.5). Laparoscopic myomectomy rates increased from 25.9% in 1998 to 41.9% in 2004; during the same period, the proportion of conversion procedures and abdominal approaches fell from 15.6% to 2.9% and 38.9% to 30.9%, respectively. Intraoperative complication rates were similar for myomectomy (1.1%) and hysterectomy (1.0%), but postoperative complication rates were higher for hysterectomy (5.8%) than myomectomy (3.2%). CONCLUSION(S): The increasing use of endoscopic procedures was an important feature in this series and appeared to be safe. The reduction of conversion rates and intraoperative complications might be related to improvements in surgical skill. Acceptance of the benefits of endoscopic approaches seems to have promoted its steady growth as a primary surgical approach.

RESUMO

Cancer care is multifactorial and patient centered. It can be described as a complex package of interventions, delivered at different times and places with different intentions, which interacts and cannot be evaluated in isolation. The authors discuss the evolving nature of cancer care and address the challenges faced by biomedical research methodology when applied to cancer care. In addition, they identify new research directions to meet these challenges. These include qualitative research, mixed methods research, and approaches based on systems thinking.

RESUMO

GOALS OF WORK: The purpose of this short review is to provide a commonly accepted definition of complementary and alternative medicine (CAM), to illustrate the widespread use of CAM by people affected by cancer around the world, and to highlight the research contributions of the Cancer Complementary and Alternative Medicine (CCAM) research team and its colleagues. METHODS: Based on research conducted by CCAM and several European colleagues, a collection of articles was compiled, reviewed, and edited. MAIN RESULTS: CAM modalities play a role in supportive care and cancer. Because of the high CAM utilization, it is critical to help cancer patients make safe, informed, evidence-based decisions for their care. In addition, advances in research methodology, outcomes, and measurement in CAM studies are suggested to better account for individual and collective experiences. CONCLUSION: This special issue provides clinicians with a summary of information about CAM and perspectives for better responding to cancer patient's needs.

RESUMO

GOALS OF WORK: This study assessed the impact of acculturation on the prevalence of traditional Chinese medicine and other complementary and alternative medicine (TCM/CAM) use in newly diagnosed Chinese cancer patients. The individual determinants of TCM/CAM use among patients were also investigated. MATERIALS AND METHODS: A consecutive sample of Chinese cancer patients treated at the British Columbia Cancer Agency was surveyed at admission using a 15-item questionnaire. Items included TCM/CAM use, sociodemographics, as well as medical and cultural factors. Data were analyzed using bivariate methods including Pearson's X (2) test and Student's t test. As well, multiple logistic regression was used to obtain the final causal model. MAIN RESULTS: Of the 230 respondents, 57% completed the survey in Chinese and 94% were immigrants. The average age was 59. Participants had a mean disease duration of approximately 2 months and 79% had already received at least one conventional treatment. Overall, TCM/CAM was used by 47% of respondents. Herbal remedies, vitamins/minerals, and prayer were the most commonly used therapies. Multivariable analysis showed that prior TCM/CAM use (p < 0.001), having received conventional treatment(s) (p = 0.029), and being less acculturated (p = 0.028) were associated with TCM/CAM use. CONCLUSIONS: Prevalence and type of use were found to vary as a function of the degree of acculturation. Health care practitioners would be well advised to discuss TCM/CAM use with their patients, especially those who are less acculturated to Western society, since they are the most likely users of TCM/CAM.
