Prospective Analysis of Food Consumption and Nutritional Status and the Impact on the Dietary Inflammatory Index in Women with Breast Cancer during Chemotherapy

Considering the implications of adverse effects of chemotherapy (CT) and the potential impact of diet on patients' recovery, this study aimed to prospectively evaluate the association between the consumption of food groups, patients' Dietary Inflammatory Index (DII®) scores, and their nutritional status. Anthropometric and dietary assessments of 55 women with breast cancer (BC) were performed at three time points. T0 is the time point after the first CT cycle, T1 is the time point after the intermediate CT cycle, and T2 is the time point after the last CT cycle. We identified a significant increase in weight, body mass index, and waist circumference during CT. Consumption of poultry and eggs was higher in T1 when compared to T2, while consumption of total fruit and total vegetables was higher at T0 compared to T1 and T2. The diet became more pro-inflammatory over the course of treatment (X2(2) = 61.127), and was related to higher abdominal adiposity. Total fruit (T0: R2 = 0.208, T1: R2 = 0.095, T2: R2 = 0.120) and total vegetable consumption (T0: R2 = 0.284, T1: R2 = 0.365, T2: R2 = 0.580) predicted DII® change at the three-time points. Meanwhile, consumption of total grains was significantly associated only with T1 (R2 = 0.084) and T2 (R2 = 0.118), and consumption of simple sugars was significantly associated only with T0 (R2 = 0.137) and T1 (R2 = 0.126). Changes in food consumption led to an increase in the inflammatory profile of the diet, suggesting the necessity to improve the guidelines during and after CT. These results reinforce the need to promote healthier eating practices in concert with maintaining a healthy nutritional status in women with BC treated with CT.

Impact of AferBio® on quality of life and chemotherapy toxicity in advanced lung cancer patients (AFERBIO study): protocol study for a phase II randomized controlled trial

BACKGROUND

Lung cancer patients undergoing palliative chemotherapy exhibit many symptoms related to the disease, such as adverse events and infectious complications during treatment, which impacts directly their health-related quality of life (HRQOL). Nutritional status is a relevant aspect among advanced cancer patients under palliative care and food supplementation has the potential to reduce treatment-related adverse effects and improve the nutritional status. The product named AferBio® is a fermented supplement that has been described as able to provide some benefits, including the capacity to potentiate the effects of anticancer drugs, by promoting the reduction of side effects and ultimately improving HRQOL.

METHODS/DESIGN

A Phase II double-blind placebo-controlled randomized clinical trial to assess the use of food supplementation with AferBio® in Stage IIIB or IV non-small cell lung cancer (NSCLC) patients beginning a second-line palliative mono-chemotherapy. The primary goal is to compare HRQOL scores between the arms of the study over time. The ten first patients included in the present study will undergo an AferBio®toxicity-testing (non-randomized phase). If no significant toxicity is found, the study will move on to the randomized phase. All patients will be randomized in blocks at a 1:1 ratio using the online tool REDCap. ECOG-PS (0-1 versus 2) criteria will be used for stratification. All patients included in the trial will be evaluated at baseline and at each chemotherapy cycle. Each evaluation will include the following: HRQOL (EORTC QLQ-C30, LC13 and IQualiV-Lung), ECOG-PS, anthropometric measurements, clinical and laboratory toxicity assessment and response evaluation.

DISCUSSION

During palliative systemic therapy in advanced cancer patients, one of the main goals is the improvement and maintenance of HRQOL, which can be negatively affected by cancer symptoms, cancer- or treatment-related psychosocial difficulties, and chemotherapy toxicity. Thus, much research has been dedicated to the development of new and more effective and/or less toxic cancer therapies. The present study is justified by the testing of a novel food supplement that may reduce some toxicities, thus, having a potential positive impact on the HRQOL of lung cancer patients. The product in question (AferBio®) is already available for sale in Brazil, but has not yet been fully tested in cancer patients.

TRIAL REGISTRATION

This Trial was registered on March 19, 2018 with ClinicalTrials.gov , NCT03469063. Protocol version: 2.0 from March 26, 2018. Trial status: Patient enrollment in the study began in April, 2018.

Missed Opportunities of Integration of Palliative Care: Frequency, Causes, and Profile of Missed Visits in an Oncologic Palliative Care Outpatient Unit

CONTEXT

Many patients with cancer are referred to palliative care (PC) outpatient clinics but do not attend consultations, which increases the difficultly of integrating PC in a timely manner.

OBJECTIVES

To evaluate the frequency, causes, and profile of missing first-time consultations in a PC outpatient clinic.

METHODS

Data from patients with advanced cancer who were scheduled for first-time visits to the PC outpatient clinic from September 2018 to August 2019 were analyzed. Missed consultation was defined as a nonperformed consultation with no prior notice of cancellation, and missed opportunity of palliative care (MOPC) was defined as a nonperformed consultation regardless of being notified in advance. The causes of the absence were identified by telephone using a standardized form. Logistic regression models were used to identify the profile of patients who have MOPC.

RESULTS

About 1468 patients were scheduled for first-time visits to the PC outpatient clinic; missed consultation = 21.7% (n = 275) and MOPC = 32.5% (n = 478). Of the total number of patients who had MOPC, 86 (18%) were later seen in a median time (percentile p25-p75) of 29.5 days (range 7.0-66.5). The most common cause of MOPC was death before consultation (n = 92; 29.8%). Referral to PC using a standardized protocol (odds ratio 0.787; P = 0.044) and residence in distant cities (odds ratio 2.394; P < 0.001) were independently associated with MOPC.

CONCLUSION

Approximately one-third of patients eligible for PC miss the opportunity to be included earlier; only 18% of them are consulted later. Use of standardized referral protocols may help to reduce these absence rates.

Longer Times of Receipt of Adjuvant Endocrine Therapy Correspond to Improved Functional Capacity and Lower Adiposity in Women Receiving Adjuvant Therapy

PURPOSE

To study the use of functional capacity (FC) level and duration of aromatase inhibitor (AI) therapy with adiposity parameters in women with breast cancer.

PATIENTS AND METHODS

FC was evaluated through the Health Assessment Questionnaire, which was assessed by classification and divided into 3 groups: G1 = mild to moderate difficulty, G2 = moderate to severe disability, and G3 = severe or very severe disability. Body mass, height, and waist circumference (WC) were measured, and body mass index (BMI) was calculated. Bioelectrical impedance analysis was used to calculate body fat (BF) and fat-free mass. The women were divided into 2 time groups (T1 and T2), which were determined by the median months of AI use (T1 ≤ 29.5 and T2 > 29.5 months).

RESULTS

Impaired FC and adiposity parameters were significantly positively correlated. In addition, physical exercise was significantly lower in women assessed as G2 and G3 compared to those assessed as G1. The effect of FC on BMI, BF, and WC was also verified, as was the effect of the duration of AI receipt on BMI and BF. Women at T1 had significantly greater functional disability, BMI, and BF values. In addition, although not statistically significant, women in T1 who were assessed as G3 presented higher BMI, WC, and BF values than those in T2.

CONCLUSION

Adiposity above the recommended parameters and impaired FC were associated with the shortest time of receipt of adjuvant endocrine therapy with AI.

"Oh, yeah, I'm getting closer to god": spirituality and religiousness of family caregivers of cancer patients undergoing palliative care

PURPOSE

Within the cancer palliative care setting, where both patients and family caregivers (FCs) undergo a transition from the end of curative treatment to palliative therapy, spirituality and religiousness (S/R) may be a strategy to help the patients and FCs better cope with the disease, in addition to exerting a positive impact on symptoms, particularly emotional symptoms. The present study aimed to understand how S/R influence FCs of cancer patients undergoing palliative care.

METHODS

This study was an exploratory and descriptive qualitative study. The qualitative approach to the data was based on Bardin's content analysis technique. The consolidated criteria for reporting qualitative research (COREQ-32) was used in the description of the results. Thirty FCs of individuals with advanced cancer undergoing palliative care were included.

RESULTS

Analysis of the FCs' narratives indicated that the FCs considered that religiousness and faith in God or a Supreme Being provide them with the strength to cope with the suffering associated with the care of relatives with advanced cancer. Many FCs emphasized that talking about God was somehow comforting and made them feel at peace with themselves. Four categories were identified in the FCs' narratives: (1) increase in faith and closeness to God becomes stronger, (2) rethink life issues, (3) negative interference in the extrinsic religiosity, and (4) quest for religiousness to gain strength or support. A conceptual framework was developed.

CONCLUSIONS

The results of the present study indicated that S/R are a coping strategy frequently used by FCs of individuals with advanced cancer. The perceptions of the FCs interviewed in the present study corresponded to the four distinct categories related to spirituality and religiousness.

The palliative care triage system in advanced cancer emergency care: development and initial validation

OBJECTIVE

We aimed to develop and validate a new emergency triage tool for use on patients with cancer undergoing palliative care (PC).

METHODS

In phase I, the new tool was developed after literature review and expert committee meetings. A prospective longitudinal study in phase II assessed the interobserver reliability of the tool. In phase III, a retrospective study of administrative data, the feasibility of routine use of the new tool and the associations with hospitalisation and survival times were evaluated.

RESULTS

The palliative care triage system (PCTS) was composed of check-list items and four colour-coded categories for maximum response time. In phase II, the PCTS was independently evaluated by two nurses for 102 attendances in the emergency department of the PC unit. An absolute agreement of 87.3% and a weighted kappa of 0.81 were observed. In phase III, all 493 attendances had the PCTS assessment registered in the medical records. The PCTS categories were associated with hospital admission (p<0.001) and survival times (p<0.001).

CONCLUSION

PCTS is a feasible tool to be used in routine ED triage of patients with advanced cancer undergoing PC. It is a valid instrument for predicting hospital admission rates and survival with high interobserver concordance rates.

Do different pedagogical conceptions result in different quality of life levels?

OBJECTIVE

The present study aims to compare medical students' quality of life (QoL) at two Brazilian institutions with different pedagogical conceptions.

METHODS

We studied students during the first four years of medical school at two institutions (one using active methodologies and small groups and the other using traditional lectures and large groups). We used a demographic questionnaire and the WHOQOL-BREF.

RESULTS

820 medical students were included. No significant differences in quality of life were found in general, nor while evaluating the course phase, except for the physical WHOQOL, which was lower for 2nd-year students at the institution with traditional lectures, even when adjusted for gender.

CONCLUSION

Our findings revealed that, despite having very distinct pedagogical conceptions and characteristics, there were no significant differences in medical students' QoL scores between both institutions. These results are surprising and differ from our initial hypothesis, which expected better QoL for those using more active and student-centered methods.

Predictors of happiness and satisfaction with life in individuals from the Brazilian general population who use social networks: a cross-sectional study

This study aimed to identify possible conditions associated with the perception of happiness and satisfaction with life in a sample of the Brazilian population who use social networks. This was a cross-sectional study with participants recruited online in five regions of Brazil via Facebook and WhatsApp. Data were collected from October 2015 to October 2016. The instruments used were the Pemberton Happiness Index, the Satisfaction with Life Scale, and a questionnaire regarding sociodemographic and clinical characteristics and issues potentially associated with the feeling of happiness. In total, 2,151 participants were included. A total of five variables exerted the greatest influence on higher levels of happiness and satisfaction with life in the multiple linear regression model, in the multiple logistic regression analysis, and in the decision tree model. Being satisfied with financial circumstances, having a positive self-evaluation of health, having frequent family gatherings, engaging in physical activity ≥ 3 times a week, and having no previous psychological/psychiatric diagnosis are variables that "seem" to positively influence Brazilians' perception of happiness and satisfaction with life. We identified some predictors of happiness and satisfaction with life, which were mainly related to the social activities and personal satisfaction of the participating individuals. Encouraging people to seek strategies for increasing levels of happiness and life satisfaction based on modifiable variables, such as those found, can be helpful in this context.

Analysis of the quality of life in patients submitted to oncological treatment of the head and neck

To evaluate the quality of life and the influence of sociodemographic and clinical variables in patients undergoing treatment for head and neck cancer. Method: Quantitative, cross-sectional study. Two instruments were used: sociodemographic and clinical questionnaire and the Functional Assessment Cancer Therapy Head Neck (FACT-HN). Results: 170 respondents, 60.6% male, 51.2% married, with laryngeal cancer being the most found (34.7%) of the total sample, 78.8% underwent surgical procedures. In FACT-HN, the variables that showed significance were: educational level, professional activity and salary income. Only in the subscale additional head and neck cancer specific concerns (HNSC) were significant: type of cancer, staging, chemotherapy and surgical treatment. Conclusions: The research contributes by showing that predictive factors of quality of life are also socioeconomic issues and not just clinical issues related to the therapeutic approach. Assistance planning is essential to provide support for rehabilitation and reintegration into society.

Relationship Between Religion/Spirituality and the Aggressiveness of Cancer Care: A Scoping Review

CONTEXT

Religiosity/spirituality/religious-spiritual coping (RS) are resources used by cancer patients with cancer to help cope with the disease and may influence the preference and receipt of end-of-life (EOL) treatment.

OBJECTIVES

To examine the relationship between RS and the EOL care preferred or received by cancer patients.

METHODS

This review protocol is registered on (International Prospective Register of Systematic Review, CRD42021251833) and follows the recommendations of the preferred reporting items for systematic reviews and meta-analyses checklist. Embase, Proquest, PubMed, Scopus, and Web of Science databases were consulted. Google Scholar was consulted for additional publications and gray literature. Quantitative studies including adults with any cancer type/stage were eligible. The paper selection was performed by two independent reviewers; the methodological quality was measured using the Newcastle Ottawa scale.

RESULTS

Seventeen studies were included in the review. In general, RS is related to the preference or receipt of aggressive EOL care and with less advance care planning. Spiritual care by the medical team is related to higher referral to hospice and less aggressive care; in contrast, high spiritual support from religious communities is associated with less hospice and more aggressive care. Religious denominations influenced health care preferences, as Catholics were less likely to sign a do-not-resuscitate order and Buddhists or Taoists received more aggressive interventions at the EOL. Most studies (70%) were of high quality according to the Newcastle Ottawa scale.

CONCLUSION

RS is associated with more aggressive EOL treatments, as well as with lower rates of ACP in cancer patients. On the other hand, spiritual care provided by the medical team seems to be associated with less aggressive EOL care.

HAprog: A New Prognostic Application to Assist Oncologists in Routine Care

CONTEXT

More patients are seeing palliative care (PC) earlier in the disease trajectory. The Barretos Prognostic Nomogram (BPN) was designed to fill the gap of survival prognostication for patients with advanced cancer and months of life expectancy. However, its routine use is limited by the common need for a ruler and calculator. Additionally, the BPN requires blood tests.

OBJECTIVES

The aim is to refine the BPN and to create a prognostic application (App) for use on smartphones.

METHODS

This is a reanalysis of the two cohorts of advanced cancer patients (development, n=215 and validation, n=276). The variable 'metastasis' was revised (volume-site combinations) and 'KPS' replaced by 'ECOG-PS'. Prognostic variables were selected for multivariable Cox and Log-logistic parametric regression analyses; the most accurate final models were identified by backward variable elimination. Calibration and discrimination properties were evaluated in the validation sample.

RESULTS

The 'full version' model is composed of 6 parameters: sex, locoregional disease, sites of metastasis, ECOG-PS, WBC and albumin. In the 'clinical version' model (5 variables), the variable 'antineoplastic treatment' was included and the laboratory variables were excluded. At validation, both models were well calibrated and presented adequate c-Index values (0.778 and 0.739). HAprog is a freely downloadable offline App that is used by clinicians to calculate prognosis in less than 1 minute.

CONCLUSION

The new models that integrate HAprog are refined prognostic tools with adequate calibration and discrimination properties. It has potential practical impact for the oncologist dealing with outpatients with advanced cancer during the decision-making process.

Absence of TGF-βRII predicts bone and lung metastasis and is associated with poor prognosis in stage III breast tumors

In the case of operated breast cancer (BC), prognostic markers help to determine if the patient needs additional treatment and predictive markers help the clinician to decide which treatment to use. Thus, a better knowledge of known predictive and prognostic markers and the identification of new markers, may improve the treatment of BC patients. The transforming growth factor-beta type II receptor (TGF-βRII), a main receptor of transforming growth factor beta pathway, is a potential new prognostic marker. The aims of the present study were to investigate both the predictive and prognostic impact of TGF-βRII in BC samples. TGF-βRII protein expression was evaluated using immunohistochemistry on a tissue microarray containing 110 TNM stage III BC samples obtained prior to doxorubicin-based neoadjuvant chemotherapy (NAC). Our results demonstrate that TGF-βRII did not predict the response to NAC. On the other hand, an association between TGF-βRII-negative tumor and higher risk of metastasis to lungs and bones was verified. TGF-βRII negativity was an independent prognostic factor for decreased disease-free and overall survival.

Prognostic value of the Global Leadership Initiative on Malnutrition criteria including systemic inflammation in patients with advanced cancer

An assessment of systemic inflammation and nutritional status may form the basis of a framework to examine the prognostic value of cachexia in patients with advanced cancer. The objective of the study was to examine the prognostic value of the Global Leadership Initiative on Malnutrition criteria, including BMI, weight loss (WL) and systemic inflammation (as measured by the modified Glasgow Prognostic Score (mGPS)), in advanced cancer patients. Three criteria were examined in a combined cohort of patients with advanced cancer, and their relationship with survival was examined using Cox regression methods. Data were available on 1303 patients. Considering BMI and the mGPS, the 3-month survival rate varied from 74 % (BMI > 28 kg/m2) to 61 % (BMI < 20 kg/m2) and from 84 % (mGPS 0) to 60 % (mGPS 2). Considering WL and the mGPS, the 3-month survival rate varied from 81 % (WL ± 2·4 %) to 47 % (WL ≥ 15 %) and from 93 % (mGPS 0) to 60 % (mGPS 2). Considering BMI/WL grade and mGPS, the 3-month survival rate varied from 86 % (BMI/WL grade 0) to 59 % (BMI/WL grade 4) and from 93 % (mGPS 0) to 63 % (mGPS 2). When these criteria were combined, they better predicted survival. On multivariate survival analysis, the most highly predictive factors were BMI/WL grade 3 (HR 1·454, P = 0·004), BMI/WL grade 4 (HR 2·285, P < 0·001) and mGPS 1 and 2 (HR 1·889, HR 2·545, all P < 0·001). In summary, a high BMI/WL grade and a high mGPS as outlined in the BMI/WL grade/mGPS framework were consistently associated with poorer survival of patients with advanced cancer. It can be readily incorporated into the routine assessment of patients.

A Research Protocol for a Phase II Single-Arm Clinical Trial Assessing the Feasibility and Efficacy of Neoadjuvant Anastrozole in Patients With Luminal Breast Cancer and Low Proliferative Index: The ANNE Trial

INTRODUCTION

Neoadjuvant endocrine therapy (NET) is recommended for the treatment of invasive breast cancer (BC), particularly luminal subtypes, in locally advanced stages. Previous randomized studies have demonstrated the benefits of aromatase inhibitors in this context. However, NET is typically reserved for elderly or frail patients who may not tolerate neoadjuvant chemotherapy. Identifying non-responsive patients early and extending treatment for responsive ones would be ideal, yet optimal strategies are awaited.

AIMS

This non-randomized phase 2 clinical trial aims to assess NET feasibility and efficacy in postmenopausal stage II and III luminal BC patients, identifying predictive therapeutic response biomarkers. Efficacy will be gauged by patients with Ki67 ≤ 10% after 4 weeks and Preoperative Endocrine Prognostic Index (PEPI) scores 0 post-surgery. Study feasibility will be determined by participation acceptance rate (recruitment rate ≥50%) and inclusion rate (>2 patients/month).

METHODS

Postmenopausal women with luminal, HER2-tumors in stages II and III undergo neoadjuvant anastrozole treatment, evaluating continuing NET or receiving chemotherapy through early Ki67 analysis after 2 to 4 weeks. The study assesses NET extension for up to 10 months, using serial follow-ups with standardized breast ultrasound and clinical criteria-based NET suspension. Clinical and pathological responses will be measured overall and in the luminal tumor A subgroup. Toxicity, health-related quality of life, and circulating biomarkers predicting early NET response will also be evaluated.

Cemiplimab plus peltopepimut-S vaccine in recurrent cervical cancer: A phase 2 clinical trial

OBJECTIVE

To estimate the clinical benefit of cemiplimab+peltopepimut-S vaccine after disease progression on first-line chemotherapy.

METHODS

This global phase 2 open-label study (NCT04646005) recruited patients with recurrent HPV16+ cervical cancer who had previously experienced disease progression after first-line chemotherapy. Patients received a total of 3 doses of peltopepimut-S vaccine on days 1, 29, and 50 and cemiplimab 350 mg every 3 weeks until disease progression or other reason for early discontinuation. Primary endpoint was objective response rate (ORR) per RECIST version 1.1; secondary endpoints were duration of response (DOR), overall survival (OS), progression-free survival (PFS), and safety.

RESULTS

Of 113 patients enrolled between June 28, 2021 and May 22, 2023, 80.5 % were white, with a median age of 49.0 years, and 58.4 % had an ECOG PS of 0. Median duration of follow-up was 4.9 months. ORR (95 % CI) per investigator assessment was 16.8 % (9.9-23.7). ORR of patients with squamous cell carcinoma by PD-L1 expression in tumor cells was 15.8 % for patients with PD-L1 < 1 % and 24.1 % for patients with PD-L1 ≥ 1 %. Median (95 % CI) DOR was 5.6 (3.5-not estimable) months. Median (95 % CI) OS and PFS were 13.3 (10.8-16.3) months and 3.0 (1.7-4.0) months, respectively. Treatment-emergent adverse events (TEAEs) occurred in 92.9 % of patients, the most common being injection-site reaction (38.9 %) and anemia (25.7 %). Six (5.3 %) patients died from a TEAE.

CONCLUSION

Cemiplimab+peltopepimut-S vaccine provides similar benefits to cemiplimab monotherapy; patients with higher PD-L1 expression in tumor cells may be more likely to benefit from treatment.

Neoadjuvant carboplatin in triple-negative breast cancer: results from NACATRINE, a randomized phase II clinical trial

BACKGROUND

Neoadjuvant chemotherapy (NACT) is the mainstay of treatment of stages II and III triple-negative breast cancer (TNBC). This study aims to evaluate if the addition of carboplatin to NACT is associated with an increase in the pathological complete response (pCR) rates in TNBC.

METHODS

We conducted an open-label phase II randomized clinical trial in a single center in Brazil. Patients with stage II and III TNBC were randomized to receive standard NACT with or without carboplatin. All the patients received doxorubicin (60 mg/m2) plus cyclophosphamide (600 mg/m2) both intravenously (i.v.) q21 days for four cycles. Patients were then randomized for additional treatment with weekly (wk) paclitaxel (80 mg/m2 i.v., for 12 cycles) plus wk carboplatin AUC 1.5 (experimental arm) or without wk carboplatin (control arm). Randomization was stratified according to gBRCA status, age, and AJCC 8th edition clinical stage (II vs. III). The primary endpoint was the pathologic complete response (pCR) rate. Secondary endpoints included recurrence-free survival and overall survival.

RESULTS

Between 2017 and 2021, 146 patients were randomized, 73 on each arm. The median age was 45 years. Most patients (66.4%) had locally advanced stage III disease, 67.1% had T3/T4 tumors, and 56.2% had clinically positive axillary lymph nodes. Germline BRCA status was available for all patients, and 19.9% had pathogenic BRCA1/2 variants. The pCR rate (ypT0ypN0) was numerically increased by 13.7%, being 43.8% (31 of 73 patients) in the experimental and 30.1% (22 of 73 patients) in the control arm, not meeting the prespecified goal of increasing the pCR in 15% (p-value = 0.08). Survival outcomes are immature.

CONCLUSION

The addition of carboplatin to standard NACT in stages II and III TNBC was associated with a non-statistically significant numerical increase in the pCR rate. Follow-up for survival outcomes and translational research initiatives are ongoing.

Eating Earlier and More Frequently Is Associated With Better Diet Quality in Female Brazilian Breast Cancer Survivors Using Tamoxifen

BACKGROUND

Emerging literature demonstrates that eating time and frequency are associated with quality and quantity of food consumption and anthropometric measurements. Considering that unhealthy dietary choices and obesity are important modifiable risk factors for breast cancer incidence and recurrence, this subject is relevant and has not been studied sufficiently in breast cancer survivors.

OBJECTIVE

This study's aim was to examine the association of eating time and frequency with diet quality, quantity of food consumption, anthropometric measurements, and body composition parameters in female breast cancer survivors using tamoxifen.

DESIGN

This was a cross-sectional study.

PARTICIPANTS/SETTING

This study was conducted from March 2015 to March 2016 at a Brazilian university hospital (Clinic's Hospital, Federal University of Uberlandia, Uberlandia, Minas Gerais, Brazil) and included an assessment of 84 female breast cancer survivors using tamoxifen (mean [SD] age was 53.1 [8.7] years).

MAIN OUTCOME MEASURES

Quantitative dietary assessment consisted of three 24-hour dietary recalls. The Brazilian Healthy Eating Index Revised was used for the qualitative diet analysis. Participants were classified by median eating time (early or late eaters of breakfast, lunch, and dinner), as well as by considering the middle time point between the first and last meal of the day (early or late midpoint eaters). Participants were also classified by median eating frequency (<5 or ≥5 eating episodes per day). Anthropometric measurements and body fat percentage by bioelectrical impedance were obtained.

STATISTICAL ANALYSIS

Generalized linear models and generalized mixed models were used to assess the associations between variables.

RESULTS

Early breakfast and dinner eating and early midpoint eating were associated with better scores for specific Brazilian Healthy Eating Index Revised components (P < .05). Early breakfast and dinner eating were also associated with better scores for the total index (P = .035 and P = .017, respectively). Early dinner eaters and early midpoint eaters had significantly lower daily energy consumption (P = .007 and P = .002, respectively). Eating ≥5 episodes per day was also associated with better scores of specific Brazilian Healthy Eating Index Revised components and the total index (P < .05). No significant associations between eating time and frequency with anthropometric measurements and body composition parameters were found (P > .05). However, women in the healthy body mass index category vs women in the overweight/obesity category had higher energy consumption at breakfast (P = .046).

CONCLUSIONS

Earlier food intake time was associated with better diet quality and lower daily energy consumption. Higher frequency of eating was also associated with better diet quality. Future studies, such as randomized controlled trials, are needed to evaluate interventions addressing the timing and frequency of meals and their effect on diet quality and quantity in breast cancer survivors.

Tumor de células germinativas de testículo simulando câncer de pâncreas

Durante as últimas duas décadas, os tumores de células germinativas de origem gonadal ou extragonadal se transformaram no modelo de tumor sólido curável, principalmente em função da boa sensibilidade à quimioterapia baseada em cisplatina. Em cerca de 90% dos casos, se apresentam com sintomas testiculares e nos casos restantes em função de metástases. Apresentamos um caso atípico que simulou inicialmente um câncer de pâncreas, atrasando o diagnóstico. Salientamos a importância de se pensar em tumor de células germinativas, principalmente em homens jovens com icterícia obstrutiva e massa em topografia de pâncreas, já que um linfonodo retroperitoneal metastático pode simular um tumor primário em pâncreas, tanto clinicamente como aos exames de imagem. Sabendo ser um câncer com tendência a rápido crescimento, mas curável em grande parte dos casos, o atraso no diagnóstico pode dificultar o tratamento de um paciente em condições inadequadas.

Validation of the Holistic Comfort Questionnaire-caregiver in Portuguese-Brazil in a cohort of informal caregivers of palliative care cancer patients

PURPOSE

The aims of this study were to perform a cross-cultural adaptation and to assess the psychometric properties of the Portuguese (Brazil) version of the Holistic Comfort Questionnaire-caregiver (HCQ-caregiver) in a sample of family caregivers (FCs) of palliative care (PC) cancer patients.

METHODS

The HCQ-caregiver was applied by a trained interviewer to a sample of 150 FCs of PC patients with advanced cancer; 50 participants were subjected to a retest 2 to 7 days after the initial test. The mean score, ceiling and floor effects, and skewness of each HCQ-caregiver item were measured. The instrument's internal consistency was assessed by means of Cronbach's alpha, and the test-retest reliability was assessed using the intraclass correlation coefficient (ICC). The convergent validity was assessed through the correlation between HCQ-caregiver and quality of life scores. Scores on the HCQ-caregiver were compared (discriminant validity) as a function of treatment setting and FC's self-perception of emotional health.

RESULTS

A ceiling effect was found in 19 items, four of which exhibited maximum response rates above 90 % and inadequate results regarding skewness. Cronbach's alpha was 0.858, and the ICC was 0.961. The scores on the HCQ-caregiver exhibited moderate-to-strong correlations with the scores of quality of life. The FCs' perceptions of comfort did not differ as a function of the treatment setting but were greater when the FCs had a better self-perception of their emotional health.

CONCLUSIONS

The present study demonstrates the validity and reliability of the Brazilian version of the HCQ-caregiver.

A Novel Detection Method of Breast Cancer through a Simple Panel of Biomarkers

Circulating tumor cells (CTCs) have been identified as responsible for the spread of tumors to other organs of the body. In this sense, the development of sensitive and specific assays for their detection is important to reduce the number of deaths due to metastases. Here, we assessed whether the detection of CTCs in peripheral blood can serve in the construction of a panel of diagnosis and monitoring treatments of breast cancer (BC), focusing on the expression of markers of epithelial-mesenchymal transition. Through analyzing the blood from women without breast alterations (control), women with benign alterations, women with breast cancer without chemotherapy, and women with breast cancer with chemotherapy, we identified the best markers by transcriptional levels and determined three profiles of CTCs (mesenchymal, intermediate, and epithelial) by flow cytometry which, combined, can be used for diagnosis and therapy monitoring with sensitivity and specificity between 80% and 100%. Therefore, we have developed a method for detecting breast cancer based on the analysis of CTC profiles by epithelial-mesenchymal transition markers which, combined, can be used for the diagnosis and monitoring of therapy.

Referral Criteria for Specialist Palliative Care for Patients With Dementia

Importance

Patients with dementia have considerable supportive care needs. Specialist palliative care may be beneficial, but it is unclear which patients are most appropriate for referral and when they should be referred.

Objective

To identify a set of consensus referral criteria for specialist palliative care for patients with dementia.

Design, Setting, and Participants

In this survey study using 3 rounds of Delphi surveys, an international, multidisciplinary panel of clinicians from 5 continents with expertise in the integration of dementia and palliative care were asked to rate 83 putative referral criteria (generated from a previous systematic review and steering committee discussion). Specialist palliative care was defined as an interdisciplinary team consisting of practitioners with advanced knowledge and skills in palliative medicine offering consultative services for specialist-level palliative care in (nonhospice) inpatient, outpatient, community, and home-based settings.

Main Outcomes and Measures

Consensus was defined a priori as at least 70% agreement among experts. A criterion was coded as major if the experts advocated that meeting 1 criterion alone was satisfactory to justify a referral. Data were summarized using descriptive statistics.

Results

Of the 63 invited and eligible panelists, the response rate was 58 (92.1%) in round 1, 58 (92.1%) in round 2, and 60 (95.2%) in round 3. Of the 58 panelists who provided demographic data in round 1, most were aged 40 to 49 years (28 of 58 [48.3%]), and 29 panelists (50%) each were men and women. Panelists achieved consensus on 15 major and 42 minor criteria for specialist palliative care referral. The 15 major criteria were grouped under 5 categories, including dementia type (eg, rapidly progressive dementia), symptom distress (eg, severe physical symptoms), psychosocial factors or decision-making (eg, request for hastened death, assisted suicide, or euthanasia), comorbidities or complications (eg, ≥2 episodes of aspiration pneumonia in the past 12 months); and hospital use (eg, ≥2 hospitalizations within the past 3 months).

Conclusions and Relevance

In this Delphi survey study, international experts reached consensus on a range of criteria for referral to specialist palliative care. With testing and validation, these criteria may be used to standardize specialist palliative care access for patients with dementia across various care settings.

Translation and cross-cultural adaptation of the Dignity Therapy Question Protocol to Brazilian Portuguese

OBJECTIVES

Dignity therapy (DT) was developed to help patients at their end of life to reframe and give meaning to their illness process. The DT question protocol focuses on personhood and important aspects of the individual's life. This study aimed to translate and culturally adapt the Dignity Therapy Question Protocol (DTQP) to Brazilian Portuguese.

METHODS

This was a descriptive and methodological study, and cross-cultural adaptation process comprised 4 stages: (1) translation and synthesis of English original version protocol into Brazilian Portuguese, (2) back translation, (3) experts committee, and (4) pretest.

RESULTS

The Portuguese version of the DTQP - Protocolo de Perguntas sobre Terapia da Dignidade - demonstrated a content validity index of 1 for all equivalences. The initial sample consisted of 41 participants (9 [21.9%] refused to participate and 1 [2.43%] dropped out). The pretest was applied to 30 (73.1%) participants, 15 of them were female and the mean age was 53.4 years. The final version consisted of 10 questions that were approved by the original authors who affirmed that the DTQP Brazilian Portuguese version maintained the original English characteristics.

SIGNIFICANCE OF RESULTS

The Brazilian cultural adaptation of the DTQP was well understood by patients. It will be very useful in palliative care clinical practice for patients nearing end of life. The adapted version to Brazilian Portuguese will facilitate future studies using the DTQP.

Cross-cultural adaptation and translation of the Pediatric Intensive Care Unit-Quality of Dying and Death into Brazilian Portuguese

OBJECTIVES

To translate and culturally adapt the Pediatric Intensive Care Unit-Quality of Dying and Death questionnaire into Brazilian Portuguese.

METHODS

This was a cross-cultural adaptation process including conceptual, cultural, and semantic equivalence steps comprising three stages. Stage 1 involved authorization to perform the translation and cultural adaptation. Stage 2 entailed independent translation from English into Brazilian Portuguese, a synthesis of the translation, back-translation, and an expert panel. Stage 3 involved a pretest conducted with family caregivers and a multidisciplinary team.

RESULTS

The evaluation by the expert panel resulted in an average agreement of 0.8 in relation to semantic, cultural, and conceptual equivalence. The pretests of both versions of the questionnaire showed that the participants had adequate comprehension regarding the ease of understanding the items and response options.

CONCLUSION

After going through the process of translation and cultural adaptation, the Pediatric Intensive Care Unit-Quality of Dying and Death caregiver and multidisciplinary team versions were considered culturally adapted, with both groups having a good understanding of the items. The questionnaires include relevant items to evaluate the process of death and dying in the intensive care setting, and suggest changes in care centered on patients and especially family caregivers, given the finitude of their children.
