Psychometric properties of the Chilean version of the quality of life questionnaire for multiple myeloma.

OBJECTIVES: To evaluate the internal consistency and construct validity of the QLQ-MY20 for assessing the quality of life in multiple myeloma survivors in Chile. METHODS: This was a cross-sectional study conducted between March 2020 and December 2022. It involved 118 individuals from two public hospitals. The QLQ-C30 and QLQ-MY20 questionnaires were used. Internal consistency was assessed using Cronbach's alpha(α), and construct validity was evaluated through hypothesis testing (Mann-Whitney and Spearman correlation). RESULTS: The average age of participants was 67.2 years (SD=9.2). Internal consistency for the complete scale was α=0.779, for the "disease symptoms" dimension α=0.671, for the "side effects of treatments" dimension α=0.538, and for the "future perspective" dimension α=0.670. Four of the five construct validity hypotheses were confirmed: women, individuals with worse performance status, those with pain, and those with worse fatigue showed more symptoms. CONCLUSIONS: The Chilean version of the QLQ-MY20 demonstrates adequate internal consistency and construct validity.

Efficacy of supervised exercise on sleep of women who survived breast cancer: a systematic review with meta-analysis.

PURPOSE: To analyze the efficacy of supervised exercise (SE) compared with control protocols on sleep parameters of women who survived breast cancer. METHODS: This systematic review with meta-analysis searched studies using the following electronic databases: PubMed, Scopus, Physiotherapy Evidence Database (PEDro), Cochrane Library, and EMBASE. The PEDro scale assessed the bias risk, and the study protocol was registered in the PROSPERO (no. CRD42023420894). RESULTS: Of 3,566 identified studies, 13 randomized clinical trials involving 847 women diagnosed with breast cancer were included. Interventions consisted of SE in an outpatient setting (62%) or combined protocols with supervised and home exercises. Most interventions (85%) used multicomponent protocols with aerobic and resistance exercises. Usual care and health education were the most reported controls. SE decreased the sleep disturbance score (- 31.61 [95% confidence interval = - 39.40 to - 23.83]) of the European Organisation for Research and Treatment of Cancer quality of life questionnaire and daytime dysfunction score (- 0.41 [95% confidence interval = - 0.73 to - 0.09]) of the Pittsburgh Sleep Quality Index (PSQI). Also, SE presented a tendency to improve the self-reported sleep quality score of the PSQI (p = 0.06). CONCLUSION: SE increased the subjective sleep quality and immobility time and decreased sleep disturbance and daytime dysfunction symptoms in women who survived breast cancer. Most SE protocols were multicomponent, with aerobic and resistance exercises ranging from moderate to high intensity. IMPLICATIONS FOR CANCER SURVIVORS: Supervised exercise may improve sleep quality and reduce symptoms of sleep disorders, contributing to survival outcomes.

Spanish version of the ICIQ-Bowel questionnaire among colorectal cancer patients: construct and criterion validity : Comprehensive assessment of bowel function.

PURPOSE: Bowel complaints are very common among patients with colorectal cancer. However, the most used questionnaires for colorectal cancer survivors do not comprehensively comprise bowel symptoms. This study aimed to examine construct and criterion validity, as well as internal consistency, of the Chilean Version of the International Consultation on Incontinence Questionnaire Bowel Module (ICIQ-B) among people with colorectal cancer. METHODS: Cross-sectional, validation study performed with 106 colorectal cancer patients from Hospital del Salvador, Chile. Bowel function was assessed with the ICIQ-B. Construct validity was assessed with confirmatory factor analysis and hypothesis testing. Specific items of a quality-of-life questionnaire (EORTC QLQ-CR29) were used to correlate with similar ICIQ-B items for criterion validity. For internal consistency, Cronbach's alpha was computed. RESULTS: For construct validity, the confirmatory factor analysis showed that the three factors model did not fit our data. Meanwhile, hypothesis testing favored the construct validity of the instrument, considering that rectal cancer patients showed worse bowel pattern (p = 0.001), bowel control (p = 0.001) and quality of life (p < 0.001) scores compared to colon cancer patients. In addition, those patients assessed before surgery also presented worse scores bowel control (p = 0.023) and quality of life (p = 0.009) compared to post-surgical patients. Regarding criterion validity, the ICIQ-B items showed a significant correlation with similar QLQ-CR29 items. The internal reliability of the instrument was good (Cronbach's α = 0.909). CONCLUSION: Considering that this questionnaire appraises bowel function in more depth, it is recommended for use in clinical practice and research with colorectal cancer patients.

Quality of Life of Chilean Breast Cancer Survivors: Multicentric Study / Qualidade de Vida de Sobreviventes de Câncer de Mama do Chile: Estudo Multicêntrico / Calidad de Vida de Sobrevivientes de Cáncer de Mama de Chile: Estudio Multicentrico

Introduction: As breast cancer survivorship rates increase, so does the necessity to improve survivors' health-related quality of life (HRQoL). Objective: To analyze HRQoL among Chilean breast cancer survivors, in general and considering geographic location. In addition, to correlate HRQoL with age, education level and body mass index (BMI). Method: Cross-sectional observational study which included 125 female breast cancer survivors from three public hospitals in three Chilean Macroregions: Central, North Central, and South. The EORTC Questionnaires, QLQ-C30 and QLQ-BR23, and sociodemographic and clinical records were applied. Results: The mean age was 56.1 (±11.9) years with a HRQoL summary score of 67.6 (21.9). HRQoL was reduced mainly in emotional functioning, pain, and insomnia. Fatigue, dyspnea, appetite loss, constipation, financial difficulties, breast and arm symptoms were also reported. The women from the South Macroregion Hospital presented the worst HRQoL scores for most of the domains [general health, functioning (physical, emotional, cognitive and social), fatigue, and nausea], p<0.001. The summary score of HRQoL was correlated to age (Spearman ́s rho=0.202, p=0.033), BMI (rho=-0.341, p<0.001), and education level (rho=0.310, p=0.001). Conclusion: Women from three Macroregions showed differences in HRQoL. The latter correlated to age, BMI, and education level. Considering the high presence of symptoms, it is necessary to improve survivorship care plans, providing access to rehabilitation in the continuum of care.

Barriers to and facilitators of adherence to pelvic floor muscle exercises and vaginal dilator use among gynecologic cancer patients: a qualitative study.

OBJECTIVE: Women with gynecologic cancer may suffer from pelvic floor dysfunction (PFD). Before radiotherapy, prehabilitation with pelvic floor muscle exercises (PFME) and vaginal dilator (VD) might prevent it and foster sexual life. This study aims to explore the experience of gynecologic cancer patients getting external beam radiation treatments regarding barriers to and facilitators of adherence to a prehabilitation program to prevent PFD. METHODS: This qualitative research with thematic content analysis included 11 women with gynecologic cancer and different levels of adherence to PFME and VD. Participants were interviewed based on a semi-structured script. The information was analyzed manually, assisted with Nvivo12® software, and triangulated with open coding. RESULTS: High self-motivation, desire to improve their health, symptoms of improvement, availability of time, the desire to resume sexual life, and the support of the partner were facilitators of adherence. The instructional exercise audio, clarity of the information, and closer communication with the physical therapist were also valued. The main barriers were general malaise secondary to oncological treatments, forgetfulness, lack of time, misinformation, lack of coordination with the treatment team, discomfort with the VD, and a feeling of shame. Feedback from the attending physician was a facilitator when present or a barrier when absent. CONCLUSION: These barriers and facilitators should be considered when designing and implementing preventive programs with PFME and VD. Behavioral counselling should consider the desire to remain sexually active; in such cases, including the partner in the therapeutic process is appraised. Otherwise, the focus should be on benefits for maintenance of pelvic floor function.

The effectiveness of different electrical nerve stimulation protocols for treating adults with non-neurogenic overactive bladder: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: Electrical nerve stimulation is a widely used treatment for overactive bladder but there is no consensus regarding the best placement of electrodes or protocols. We hypothesised that some non-implanted neurostimulation protocols would be more effective compared to others for treating urinary symptoms and improving quality of life among adults diagnosed with non-neurogenic overactive bladder. METHODS: A systematic review and meta-analyses of randomized clinical trials were performed in five electronic databases: PubMed/MEDLINE, Lilacs, CINAHL, Web of Science, and PEDro. The main outcome was urinary symptoms-frequency, nocturia, and urgency-and the secondary outcome quality of life. Some protocol characteristics were extracted, e.g., frequency, pulse width, intensity, intervention time, and electrode placement. RESULTS: Nine randomized controlled trials were included. Tibial neurostimulation showed better results than sacral neurostimulation for urge incontinence (mean difference = 1.25 episodes, 95% CI, 0.12-2.38, n = 73). On the pooled analysis, the different neurostimulation protocols-intravaginal, percutaneous tibial, and transcutaneous tibial nerve stimulation-demonstrated similar results for urinary frequency, nocturia, and urgency as well as quality of life. In general, effect sizes from meta-analyses were low to moderate. The best reported parameters for percutaneous tibial nerve stimulation were 20-Hz frequency and 200-µs width, once a week. CONCLUSIONS: There was evidence that tibial neurostimulation is more effective than sacral neurostimulation for urge incontinence symptoms among patients with non-neurogenic overactive bladder. Overall, there was no superiority of an electrical nerve stimulation electrode placement and protocol over others considering urinary symptoms and quality of life. Further studies with three-arm trials are necessary. This study was registered at PROSPERO: CRD4201810071.

Pad test for urinary incontinence diagnosis in adults: Systematic review of diagnostic test accuracy.

INTRODUCTION: The pad test is an assessment tool for urinary incontinence (UI) severity classification and therapeutic response monitoring. However, the reliability and reproducibility of this test have been questioned. OBJECTIVES: To summarize the evidence regarding the accuracy measures and reproducibility of different pad test protocols for assessing UI. METHODS: A systematic review of the diagnostic accuracy of this tool was performed (CRD42020219392). ELIGIBILITY CRITERIA: Studies reporting data on the accuracy measures and reproducibility of the pad test when used for detecting UI in adult men and women. DATA SOURCES: MEDLINE, Science Direct, Cochrane, Web of Science, LILACS, and Pedro. DATA EXTRACTION AND SYNTHESIS: Two reviewers independently screened the articles, extracted the data, and evaluated the risk of bias (RoB) using the QUADAS-2 tool. RESULTS: From 1048 studies, 18 studies were included. Eight of these reported accuracy data, and 12 reported reproducibility properties. A total of 1070 individuals were analyzed, whose mean age ranged from 20 to 90 years. The accuracy of the long-duration protocols was generally moderate to high (sensitivity, 60%-93%; specificity, 60%-84%). The 1-h protocols obtained higher accuracy values. The overall reproducibility was moderate to high (κ ≥ 0.66). LIMITATIONS: The RoB was high and, due to different cutoff points adopted by studies, the bivariate model was not satisfied to perform a meta-analysis. DISCUSSION: The 1-h pad test was more accurate but less reproducible when compared to the long-duration tests. Pad test results should be used with caution in clinical practice.

Spanish translation, face validity, and reliability of the ICIQ-B questionnaire with colorectal cancer patients

Purpose: To describe the English-to-Spanish translation process and preliminary psychometric analysis (face validity, cultural adaptation, and test-retest reliability) of the International Consultation on Incontinence Questionnaire - Bowels Module (ICIQB) among Chilean colorectal cancer patients. Materials and Methods: The face validity was studied with 10 colorectal cancer patients, and the test-retest reliability, with 15 patients, 1 month before and 6 months after cancer surgery. Results: Two rounds of translation/back translation resulted in a Spanish version. The English expression open your bowels was translated as defecar, as it is easily understandable in Spanish. The patients reported that the instrument was easy to answer, with clear instructions, and that it was adequate to appraise their health condition. The testretest reliability was good (Spearman rho [ρ] ≥ 0.842); only item 15a, the Bristol Stool Scale, obtained a moderate correlation (ρ=0.639). The patients reported a variety of symptoms, including increased bowel movements, nocturnal bowel movements, fecal urgency, and incontinence. Conclusions: The first Spanish version of the ICIQ-B was culturally adapted for Chilean colorectal cancer patients, and showed good test-retest reliability. It might be a reference for other Spanish-speaking countries and for patients with other conditions. The ICIQ-B is a robust comprehensive questionnaire for bowel function. (AU)

A randomized clinical trial to assess the effectiveness of pre- and post-surgical pelvic floor physiotherapy for bowel symptoms, pelvic floor function, and quality of life of patients with rectal cancer: CARRET protocol.

BACKGROUND: There is scarcity of trials about preventative strategies for low anterior resection syndrome (LARS) in rectal cancer patients. The aim of this study is to evaluate the effectiveness of a pre- and post-surgical pelvic floor rehabilitation program on the bowel symptoms, pelvic floor function, and quality of life of rectal cancer patients. METHODS: A randomized controlled trial with parallel groups (pelvic floor rehabilitation versus control group), with a blinded evaluator. PARTICIPANTS AND SETTING: 56 stage I to III rectal cancer patients aged from 18 to 80 years old undergoing sphincter preservation surgery at Hospital del Salvador and who have a sufficient knowledge of Spanish. MAIN OUTCOME MEASURES: ICIQ-B questionnaire for intestinal symptoms, high-resolution anorectal manometry (Alacer Multiplex 24-channel manometry equipment) for anorectal function, pelvic floor muscle strength test with Oxford Modified Scale, and a quality of life test with the EORTC QLQ C30 questionnaire. The evaluations will be carried out at five stages: before surgery, before and after the pelvic floor rehabilitation, and during a 3-month and 1-year follow-up. INTERVENTIONS: one pre-rehabilitation session and 9 to 12 sessions of pelvic floor rehabilitation, including patient education, pelvic floor muscle exercises, pelvic floor electromyography biofeedback, and capacitive and sensory rectal training with a balloon probe. Rehabilitation will begin 3-5 weeks before the ileostomy is removed (four sessions) and around 3 weeks after stoma removal (5-8 sessions). DISCUSSION: We expect the program to improve the bowel symptoms, pelvic floor function, and quality of life of rectal cancer patients. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Register ACTRN12620000040965 . Registered on 21 January 2020.

Comparison between Two Methods to Evaluate Function in Postoperative Breast Cancer Survivors.

INTRODUCTION: Treatment for breast cancer can cause adverse effects such as pain and reduced upper limb function which can affect activities of daily living. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire is the most used tool for evaluating function in breast cancer survivors. However, some specific aspects have raised discussions about its restricted coverage, which can generate several biases. OBJECTIVE: To determine if DASH scores differed when assessed before and after task-oriented training (TOT) at 3 and 6 months after breast cancer surgery. DESIGN: Prospective cohort study. SETTING: Institutional study of 22 women assessed at 3 and 6 months after breast cancer surgery. MAIN OUTCOME MEASURES: The DASH questionnaire and TOT assessment. Two correlation tests were performed: Spearman's correlation between the total score of the two DASH scores (pre- and post-TOT) and the Kendall's tau correlation between each of the items. RESULTS: There was a moderate and excellent correlation between final DASH scores, pre- and post-TOT, at both 3 and 6 months postoperatively. However, when assessed individually, most of the DASH items were poorly correlated. There was also no agreement between the total DASH scores pre- and post-TOT as assessed by Bland-Altman plots. CONCLUSION: Both the DASH and TOT are considered useful in clinical practice to assess upper limb function, although the use of TOT in some of the DASH items may reduce memory bias and improve skills estimation.

Functional outcomes and oncological fatigue among older cancer patients: a cross-sectional study

Abstract Aim: To characterize functional outcomes and oncological fatigue in older cancer patients, and verify the relation of these outcomes with age, number of hospitalizations, and falls within 12-months. Methods: Cross-sectional study involving 116 older adults with cancer undergoing treatment in a hospital in Santiago de Chile. Participants were assessed for independence on the activity of daily living (Barthel index), functional mobility with "timed up and go" (TUG) test, handgrip strength with a Baseline® Hydraulic Hand Dynamometer, and fatigue with Brief Fatigue Inventory. Information about the number of falls and hospitalizations from the previous 12-months was also collected. Results: 21.6% had experienced at least one fall during the previous 12-months, and 52% had been hospitalized over the same period. Handgrip strength was below the cut-off thresholds for older adults and 78.4% were classified with the risk of falls according to the TUG test. Forty-nine percent of participants experienced moderate fatigue, and 58% were dependent to perform activities of daily living. There was a correlation of TUG results with age (r = 0.204; p = 0.028). Conclusions: Older adults with cancer in our study experienced moderate fatigue, a high dependence to perform activities of daily living, especially those associated with mobility, dressing, and bladder or bowel function. Older adults with cancer are more likely to develop functional decline which leads to increased dependency or death. The data suggests they present functional impairment. Physical activity interventions would benefit this population.

Functionality and factors associated with work behaviour among Brazilian breast cancer survivors: A cross-sectional study.

BACKGROUND: Breast cancer treatments lead to several comorbidities in the upper limbs, such as pain and stiffness, hindering physical functions and the return to work. OBJECTIVE: To explore the functionality and factors associated with work behaviour among manual and non-manual Brazilian workers who have recovered from breast cancer. METHODS: This is an observational cross-sectional study involving Brazilian breast cancer survivors. The sociodemographic, work, and clinical aspects were assessed through clinical records, upper limb disability, and human functionality obtained from 62 women. Multiple and univariate logistic regressions were used to identify the association of variables on return to work, p < 0.05. RESULTS: 56.5% of women did not return to work, the mean time for returning to work was 16 months (±15.21), absenteeism from work lasted 41 months (±34.58). Modified radical mastectomy (OR = 5.13, 95% CI = 1.35 to 18.66) and moderate-to-severe disability levels in the upper limbs (OR = 6.77, 95% CI = 1.86 to 24.92) were associated with not returning to work. The loss of productivity was higher among non-manual workers (21.5%) (p = 0.040). CONCLUSIONS: The rates of not returning to work after breast cancer treatment are high. Women who did not return to work presented higher levels of disability.

Pre-rehabilitation of the pelvic floor before radiation therapy for cervical cancer: a pilot study.

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate pelvic floor muscle (PFM) function regarding strength, activation and incontinence, approximately 1 month before and after radiation therapy in women with cervical cancer. METHODS: This was a pilot study of 49 women with cervical cancer at stages I to III. These women attended an educational session with a physical therapist who taught them to perform preventive pelvic floor muscle exercises (PFMEs; slow and fast contractions and the "knack") at home before, during and after radiation therapy. The women received instructions for performing PFME prior to radiation therapy. The modified Oxford scale, electromyography (EMG), the International Consultation on Incontinence Questionnaire Short Form to assess urinary incontinence and two questions for faecal and gas incontinence were used. RESULTS: Twenty-eight women (57%; mean age = 44 years, range 27-66) completed the study, 21 (43%) were lost to follow-up. There was no significant change from baseline to post-radiation therapy in muscle strength, EMG records and incontinence (p > 0.05). The median of PFM strength was equal at baseline and after intervention (median = 2; IQR = 1). CONCLUSIONS: The results of this study suggest that pre-rehabilitation teaching PFMEs might be a protective factor for preserving PFM strength and preventing incontinence 1 month after radiation therapy. It is a feasible intervention.

Vaginal Dilator and Pelvic Floor Exercises for Vaginal Stenosis, Sexual Health and Quality of Life among Cervical Cancer Patients Treated with Radiation: Clinical Report.

This clinical report aimed to evaluate the effectiveness of the combination of vaginal dilator (VD) and pelvic floor muscle exercises (PFME) on vaginal stenosis, sexual health and quality of life among women undergoing radiotherapy treatment for cervical cancer; PFME were instructed prior to radiotherapy with six-month follow-up. An intention-to-treat analysis was performed for the 28 women. At four-months after radiotherapy, most of the women (90.9%) maintained/increased one size of the VD and were sexually active (81.8%). Adherence to VD was high. Regarding quality of life, there was more limitation in emotional functioning. VD and PFME were effective at preventing stenosis.

Physical symptoms and components of labor tasks associated with upper limb disability among working breast cancer survivors.

BACKGROUND: Each year, the number of breast cancer (BC) cases increases in Brazil and worldwide. In addition, BC affects women of working age who need to resume their jobs after treatments. This is an observational, cross-sectional study that investigated the association of physical symptoms and work tasks with upper limb disability and return to work in BC survivors. METHODS: Sociodemographic, labor, clinical and surgical aspects, and physical incapacity of the upper limbs of 62 women diagnosed with BC were evaluated through a questionnaire of our own and the disability of the arm, shoulder, and hand (DASH) questionnaire. The data were analyzed by the IBM Statistical Package for Social Sciences SPSS version 20.0 and a significance of p < 0.05 was adopted. Logistic regression and odds ratio were used to verify the level of association between work tasks and pain with return to work, and multiple linear regression verified the association of physical symptoms with upper limb functionality. RESULTS: The work tasks associated with non-return to work were raising objects above the head (OR 3.64, 95% CI 1.26-10.51), lifting objects of more than 5 kg (OR 2.88, 95% CI 1.02-8.13), and loading objects of more than 5 kg (OR 3.93; 95% CI 1.14-10.07). The pain in the upper quadrant homologous to the surgery explained 64% of the variance in physical incapacity of the upper limbs. CONCLUSIONS: There is an association of labor tasks that require upper limb strength and range of motion with non-return to work, and also pain in the upper quadrant homologous to the BC with reduction in the functionality of the upper limbs.
