Safety of weightlifting among women with or at risk for breast cancer-related lymphedema: musculoskeletal injuries and health care use in a weightlifting rehabilitation trial.

ABSTRACT: INTRODUCTION:It has been noted that only 14% of all clinical trials are translated into practice. The objective of this paper is to promote translation of an efficacious rehabilitative exercise program for breast cancer survivors by clarifying for clinicians the safety profile of participants (e.g., rates of musculoskeletal injury and referral to medical professionals), and to use this evidence to make recommendations on the appropriate training of health and fitness staff who would be capable of safely, effectively, and sustainably delivering the program. METHODS:Breast cancer survivors with and at risk for lymphedema were randomized to twice-weekly weightlifting or standard care for 1 year. An injury survey and health care evaluation were administered after 1 year and in 3-month intervals, respectively. RESULTS:The cumulative incidence and rate of injury were higher in the weightlifting than in the control group. The injury rates were 2.3 and 0.3 per 1,000 bouts of weightlifting among breast cancer survivors with and at risk for lymphedema, respectively. Among breast cancer survivors with or at risk for lymphedema, 20.9% in the weightlifting group had an encounter with a health care provider that required cessation or dose modification of weightlifting. CONCLUSION:Despite the demonstrated efficacy of weightlifting, musculoskeletal injuries and other health problems did occur. Therefore, for the successful translation of this rehabilitative intervention into clinical practice, health and fitness professionals working with breast cancer survivors need the knowledge, skills, and abilities that clarify their scope of practice to address these health care needs.

Project description:To profile the prescription for and adherence to breast cancer-related lymphedema (BCRL) self-care modalities among breast cancer (BrCa) survivors with BCRL in a 12-month randomized weightlifting trial.We developed a questionnaire that assessed prescription for and adherence to 10 BCRL self-care modalities that included physical therapy exercise, pneumatic compression pump, medication, lymphedema bandaging, arm elevation, self-administered lymphatic drainage, therapist-administered lymphatic drainage, compression garments, skin care, and taping. We measured prescription for and adherence to BCRL self-care modalities at baseline, 3, 6, and 12 months. Longitudinal logistic regression was used to estimate the odds ratio (OR) and 95 % confidence interval (95 % CI) associated with prescription for and adherence to BCRL modalities over time.This study included 141 BrCa survivors with BCRL. Women were prescribed an average of 3.6?±?2.1 BCRL self-care modalities during the study. The prescription for therapist-administered lymphatic drainage (OR?=?0.92, 95 % CI 0.88-0.96), pneumatic compression pump use (OR?=?0.94, 95 % CI 0.89-0.98), and bandaging (OR?=?0.96, 95 % CI 0.93-0.99) decreased over 12 months of follow-up. No other prescribed BCRL self-care modalities changed during the study. Over 12 months, the average adherence to all BCRL self-care modalities varied with 13, 24, 32, and 31 % of women reporting <25, 25-49, 50-74, and ?75 % adherence, respectively. Over 12 months, there was a noticeable change from high to low adherence in self-administered lymphatic drainage, such that there was a 15 % increased likelihood of adherence <25 % compared to ?75 % (OR?=?1.15 (95 % CI 1.05-1.26); p?=?0.002). The adherence patterns of all other modalities did not change over follow-up.Our findings suggest the prescription for BCRL self-care modalities is variable. The average adherence to BCRL self-care was non-optimal. Future research is necessary to prepare BrCa survivors with the knowledge, skills, abilities, and resources necessary to care for this lifelong condition.

Project description:Breast cancer tends to occur in an older age group of women also burdened with comorbidities such as cardiovascular disease (CVD). Numerous medications used to manage CVD (e.g., statins and antihypertensives) are hypothesized to alter breast cancer risk, but there are few studies on breast cancer outcomes. The COmmonly used Medications and Breast Cancer Outcomes (COMBO) cohort was developed to study how medications and co-morbidities influence breast cancer prognosis. Cohort study among adult women, diagnosed with incident early stage breast cancer, and enrolled in an integrated health plan. Data sources included health plan administrative databases, Surveillance, Epidemiology, and End Results tumor registry, and medical records. Statins, angiotensin-converting enzyme inhibitors (ACEI), beta blockers (BB), calcium blockers, and diuretics were the exposures of interest. The outcome was second breast cancer events (SBCE) defined as recurrence or second primary breast cancer. We used multivariable Cox proportional hazards models to estimate hazard ratios (HR) and 95 % confidence intervals (CI) for SBCE, and components of SBCE. 4,216 women were followed for a median of 6.3 years, and 13.2 % experienced a SBCE (first of: n = 415 recurrences and n = 143 s primary breast cancers). Compared to non-users, we observed an increased risk of second primary breast cancer with ACEI use (HR = 1.66; 95 % CI, 1.06-2.58) and an increased risk of recurrence with BB use (HR = 1.29; 95 % CI, 1.01-1.64). There was suggestion of a reduced risk of SBCE with statin use (HR = 0.82; 95 % CI, 0.62-1.08) and second primary breast cancer with BB use (HR = 0.77; 95 % CI, 0.50-1.19). No differences in outcomes were observed by duration of medication use. A majority of CVD medications evaluated in this study appear safe with respect to SBCE, but ACEI and BB use warrant further evaluation. The study presented is one example of the questions that can be addressed using the COMBO cohort.

Project description:INTRODUCTION:Current evidence suggests that patients who have latissimus dorsi (LD) breast reconstruction following mastectomy for breast cancer can experience long-term shoulder dysfunction. However, as there is no standardised assessment or follow-up period within the literature, findings are conflicting. This research aimed to investigate the impact on daily living of immediate and delayed LD breast reconstruction in women following mastectomy for breast cancer. METHODS:Both qualitative and quantitative methods of enquiry were used. A focus group study explored the musculoskeletal consequences of surgery as perceived by the women (n = 15) and their healthcare professionals (n = 11). A questionnaire survey was administered (n = 159), including a range of outcome measures to quantify both the physical and psychosocial impact of LD breast reconstruction. Dyad interviews were also conducted in order to determine the impact of surgery on function and activities of daily living (ADL) from the woman's perspective and that of her significant other (n = 8). RESULTS:The qualitative studies highlighted a lack of preparedness and unrealistic expectations regarding functional recovery among women and their significant others'. Post-surgery it was apparent that women weighed up reduced shoulder function against survival, demonstrating resilience in their approach to coping with this adaptive way of living. The survey identified low to moderate effect on the outcomes assessed (n = 159), however, node removal significantly impacted certain aspects of quality of life (p<0.05) and disability (p = 0.04). CONCLUSIONS:Breast reconstruction using the LD had an impact on shoulder function and some ADL, which impacted not only on the women but also family and significant others. Despite the functional implications associated with surgery, findings would suggest that shoulder dysfunction is not their main concern. This work identified that women and their significant other require further information to clarify expectation regarding recovery, highlighting the changing priorities of women throughout their journey from diagnosis into long-term recovery.

Project description:BACKGROUND:Pediatric musculoskeletal injuries cause moderate to severe pain, which should ideally be addressed upon arrival to the emergency department (ED). Despite extensive research in ED-based pediatric pain treatment, recent studies confirm that pain management in this setting remains suboptimal. The No OUCH study consist of two complementary, randomized, placebo-controlled trials that will run simultaneously for patients presenting to the ED with an acute limb injury and a self-reported pain score of at least 5/10, measured via a verbal numerical rating scale (vNRS). Caregiver/parent choice will determine whether patients are randomized to the two-arm or three-arm trial. In the two-arm trial, patients will be randomized to receive either ibuprofen alone or ibuprofen in combination with acetaminophen. In the three-arm trial, patients can also be randomized to a third arm where they would receive ibuprofen in combination with hydromorphone. This article details the statistical analysis plan for the No OUCH study and was submitted before the trial outcomes were available for analysis. METHODS/DESIGN:The primary endpoint of the No OUCH study is self-reported pain at 60?min, recorded using a vNRS. The principal safety outcome is the presence of any adverse event related to study drug administration. Secondary effectiveness endpoints include pain measurements using the Faces Pain Scale-Revised and the visual analog scale, time to effective analgesia, requirement of a rescue analgesic, missed fractures, and observed pain reduction using different definitions of successful analgesia. Secondary safety outcomes include sedation measured using the Ramsay Sedation Score and serious adverse events. Finally, the No OUCH study investigates the reasons given by the caregiver for selecting the two-arm (Non-Opioid) or three-arm (Opioid) trial, caregiver satisfaction, physician preferences for analgesics, and caregiver comfort with at-home pain management. DISCUSSION:The No OUCH study will inform the relative effectiveness of acetaminophen and hydromorphone, in combination with ibuprofen, and ibuprofen alone as analgesic agents for patients presenting to the ED with an acute musculoskeletal injury. The data from these trials will be analyzed in accordance with this statistical analysis plan. This will reduce the risk of producing data-driven results and bias in our reported outcomes.

Project description:ObjectivesWe have previously developed and validated the Arthritis Research UK Musculoskeletal Health Questionnaire (MSK-HQ) for use across musculoskeletal care pathways, showing encouraging psychometric test results. The objective of this study was to determine the responsiveness of MSK-HQ following MSK treatments and to determine the minimally important change (MIC).SettingWe collected data in four cohorts from community physiotherapy and secondary-care orthopaedic hip, knee and shoulder clinics.Participants592 individuals were recruited; 210 patients treated with physiotherapy for a range of MSK conditions in primary care; 150 patients undergoing hip replacement, 150 patients undergoing knee replacement and 82 undergoing shoulder surgery in secondary care.Outcome measuresPreoperative data were collected including the MSK-HQ, European Quality of Life-5D (EQ-5D) and the OHS, OKS or OSS in each joint-specific group. The same scores, together with anchor questions, were collected postintervention at 3 months for the physiotherapy group and 6 months for all others. Following COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) guidelines, responsiveness was assessed using correlation between scores and the MIC was calculated for the entire cohort using receiver operating characteristic curve analysis.ResultsThe MSK-HQ demonstrated strong correlation (R=0.73) with EQ-5D across the entire cohort and with each of the joint-specific Oxford scores (hip R=0.87, knee R=0.92?and shoulder R=0.77). Moderate correlation was seen between MSK-HQ and EQ-5D across each individual group (R value range 0.60-0.68), apart from the hip group where correlation was strong (R=0.77). The effect size with MSK-HQ was 0.93, in the entire cohort, double that measured with EQ-5D (0.43). In all subgroups, MSK-HQ measured a greater treatment effect compared with EQ-5D. The MIC is 5.5 (95% CI 2.7 to 8.3).ConclusionOur study demonstrates that the MSK-HQ questionnaire is responsive to change across a range of musculoskeletal conditions, supporting its use as a generic MSK measurement instrument.
