Nutritional Intervention Contributes to the Improvement of Symptoms Related to Quality of Life in Breast Cancer Patients Undergoing Neoadjuvant Chemotherapy: A Randomized Clinical Trial.

During breast cancer treatment, worsening quality of life (QoL) and the presence of toxicities are common, but healthy eating practices are associated with better clinical results. Thus, this study aims to evaluate the effect of a nutritional intervention on QoL and on gastrointestinal and hematological toxicities resulting from chemotherapy in women with breast cancer. A randomized clinical trial was performed at the beginning of neoadjuvant chemotherapy treatment for women with breast cancer. All participants received nutritional advice on healthy eating practices, but only the intervention group (IG) received an individualized diet plan. The study enrolled 34 women, 19 in the IG and 15 in the control group (CG). During the study, the CG significantly presented a reduction (from 21.6 ± 5.9 kg to 18.8 ± 4.0 kg, p = 0.009) in handgrip strength (HGS), while the IG did not present changes in this variable. Regarding QoL, the IG preserved the role function during treatment and presented better results for nausea/vomiting and loss of appetite compared to the CG. In gastrointestinal and hematological toxicities, the IG had lower frequencies of leukopenia and abdominal pain. The nutritional intervention preserved the role function of QoL and HGS, reduced the occurrence of nausea/vomiting, loss of appetite and the frequency of leukopenia and abdominal pain.

Risk factors associated with antineoplastic chemotherapy-induced nausea and vomiting.

OBJECTIVE: To estimate the incidence and to evaluate risk factors for antineoplastic nausea and vomiting with high and moderate emetogenic chemotherapy in adult patients in the first treatment cycle. METHODS: Prospective cohort study with follow-up of 269 adults during the first cycle of antineoplastic chemotherapy. The incidence of nausea and vomiting was evaluated in the acute phase (0-24 hours), in the late phase (24 hours-5th day) and in the total phase (0-5th day). RESULTS: In total, 152 patients underwent high emetogenic chemotherapy and 117 moderate emetogenic chemotherapy. The relative frequency of nausea was higher when compared with vomiting in the acute phase (p < 0.001) and in the late phase (p < 0.001). The risk factors identified were: age group ≤ 49 years (odds ratio = 0.47; 95%CI 0.23-0.95) and 50-64 years (odds ratio = 0.45; 95%CI 0.23-0.87), tobacco use (odds ratio = 0.35; 95%CI 0.14-0.88), and high emetogenic chemotherapy (odds ratio 0.55; 95%CI 0.31-0.95). CONCLUSION: The incidence of nausea was higher than that of vomiting, and adverse effects were more frequent in the late phase. The results suggest the risk factors for chemotherapy-induced nausea and vomiting are tobacco, age (young adults), and high emetogenic chemotherapy.

Children with Functional Nausea-Comorbidities outside the Gastrointestinal Tract.

OBJECTIVE: To detail common comorbidities and procedures performed to evaluate functional nausea in children. STUDY DESIGN: In total, 63 children age 7-18 years seen in a tertiary care pediatric clinic who met Rome IV criteria for functional nausea prospectively completed an Intake Questionnaire, the Pediatric and Parent-Proxy PROMIS-25 Profile v 2.0, the Pediatric and Parent-Proxy Pediatric Sleep Disturbance-Short Form 4a, and the COMPASS 31 orthostatic intolerance scale to assess comorbidities. Medical records were reviewed for diagnostic tests performed to evaluate nausea and for additional comorbidities. Summary statistics were used to determine the most common comorbidities and diagnostic yield of the procedures. Intraclass correlation coefficients assessed agreement between parent and child reports on the PROMIS scales. RESULTS: Patients with functional nausea experienced multisystem comorbidities. A majority reported abdominal pain, headache, orthostatic intolerance, fatigue, disturbed sleep, anxiety, constipation, allergies, and vomiting. Agreement between parent-proxy and child report of symptoms on PROMIS scales was good to excellent (intraclass correlation coefficients = .78-.83; all P < .001). Patients underwent extensive diagnostic testing: 96 endoscopic procedures, 199 radiologic tests, and 4 cholecystectomies. Most of the procedures were not diagnostically informative. CONCLUSIONS: Children with functional nausea have comorbidities outside the gastrointestinal tract that warrant evaluation. Gastrointestinal diagnostic tests were of low-yield in identifying a cause. Understanding the relationship with comorbidities may provide insight into etiologies for the nausea and define clinical phenotypes to better tailor care.

The Effect of the Intra-gastric Balloon on Gastric Emptying and the DeMeester Score.

BACKGROUND AND AIMS: The mechanism of weight loss with the intra-gastric balloon (IGB) is thought to be a decrease in gastric emptying (GE); however the evidence is conflicting. Nausea, abdominal pain, and gastroesophageal reflux disease (GERD) can cause intolerance resulting in early removal. This is demoralizing for the patient and costly for the healthcare system. The ability to predict which patients will have superior weight loss and tolerance is invaluable. We sought to investigate if the IGB induced weight loss by reducing GE and the effect of the IGB on the DeMeester score. METHODS: We retrospectively reviewed prospectively collected data for patients undergoing IGB placement at a single hospital. Manometry and pH studies were performed before and with the IGB in place. Weight was measured at baseline, at removal, and 6 months later. Adverse events leading to early removal were recorded. RESULTS: Twenty-four patients were evaluated. There was a statistically significant decrease in GE for solids with the IGB (117.92 ± 150.23 vs 281.48 ± 206.49 min; p = 0.0048), but not for liquids (54.44 ± 17.97 vs 56.08 ± 43.96 min; p = 0.7228). The lower esophageal sphincter (LES) pressure did not change significantly with placement of the IGB (17.76 ± 7.39 vs 14.74 ± 7.24 mmHg; p = 0.09). On multivariate analysis, increase in DeMeester score was associated with total body weight loss (p = 0.0125) and change in GE (p = 0.038) independently. CONCLUSION: The IGB delays GE for solids, but not for liquids, and increases the DeMeester score by a mechanism other than a loss of LES pressure.

Risk factors associated with antineoplastic chemotherapy-induced nausea and vomiting / Fatores de risco associados a náuseas e vômitos induzidos por quimioterapia antineoplásica

CONCLUSION: The incidence of nausea was higher than that of vomiting, and adverse effects were more frequent in the late phase. The results suggest the risk factors for chemotherapy-induced nausea and vomiting are tobacco, age (young adults), and high emetogenic chemotherapy.

RESUMO OBJETIVO: Estimar a incidência e avaliar os fatores de risco para náuseas e vômitos induzidos por antineoplásicos com alto e moderado potencial emético em pacientes adultos, no primeiro ciclo de tratamento. MÉTODOS: Estudo de coorte prospectiva, com 269 adultos acompanhados durante o primeiro ciclo de quimioterapia antineoplásica. A incidência de náuseas e vômitos foi avaliada na fase aguda (0-24 horas), na fase tardia (24 horas-5° dia) e na fase total (0-5° dia). RESULTADOS: 152 pacientes foram submetidos a quimioterápico com alto potencial emético e 117 a moderado potencial emético. A frequência relativa de náuseas foi maior quando comparada à de vômitos na fase aguda (p < 0,001) e na fase tardia (p < 0,001). Os fatores de risco identificados foram: faixa etária ≤ 49 anos (odds ratio = 0,47; IC95% 0,23-0,95) e 50-64 anos (odds ratio = 0,45; IC95% 0,23-0,87), uso de tabaco (odds ratio = 0,35; IC95% 0,14-0,88) e alto potencial emético dos quimioterápicos (odds ratio 0,55; IC95% 0,31-0,95). CONCLUSÃO: A incidência de náuseas foi maior do que a de vômitos, e na fase tardia os efeitos adversos foram mais frequentes. Os resultados sugerem que os fatores de risco para náuseas e vômitos induzidos por quimioterapia são o tabaco, a idade (adultos jovens) e o alto potencial emético do quimioterápico.

Health Outcomes and Quality of Life Indices of Children Receiving Blenderized Feeds via Enteral Tube.

OBJECTIVE: To determine whether clinical and patient-reported outcomes differ in children receiving blenderized diets compared with conventional formula. STUDY DESIGN: We conducted a prospective cohort study of 70 children aged 1-18 years receiving blenderized diets vs conventional formula via feeding tube. We assessed rates of hospitalization and visits to the emergency department (ED) at Boston Children's Hospital in 2017 and Likert scale addressing satisfaction with feeding regimen; Pediatric Gastroesophageal Reflux Disease Symptom and Quality of Life Questionnaire; Pediatric Quality of Life Inventory; and Pediatric Quality of Life Inventory Gastrointestinal Symptoms Scale. RESULTS: Participants receiving blenderized diets (n = 42, 60%) did not differ in demographics or comorbid diagnoses from those receiving conventional formula (n = 28, 40%). Rates of total visits to the ED (0.8 ± 1.5 vs 1.4 ± 2.7, P = .05), total admissions (0.8 ± 1.2 vs 1.7 ± 2.3, P = .01), and respiratory-related admissions (0.2 ± 0.5 vs 0.6 ± 0.8, P = .04) per year were significantly lower in participants receiving blenderized diets, and respiratory-related visits to the ED trended toward significance (0.1 ± 0.4 vs 0.4 ± 0.8, P = .08). Compared with those receiving conventional formula, participants on blenderized diets reported greater satisfaction ratings (Likert scale 4.3 ± 1.0 vs 3.3 ± 1.2, P = .001), lower symptom (0.7 ± 0.8 vs 1.2 ± 1.1, P = .03), and total (0.8 ± 0.8 vs 1.2 ± 1.0, P = .02) scores on Pediatric Gastroesophageal Reflux Disease Symptom and Quality of Life Questionnaire and greater scores on the Pediatric Quality of Life Inventory Gastrointestinal Symptoms Scale, indicating less nausea and vomiting (64.0 ± 22.6 vs 49.0 ± 37.9, P = .02), abdominal pain (65.0 ± 26.8 vs 56.4 ± 33.9, P = .04), diarrhea (87.9 ± 15.5 vs 73.6 ± 26.3, P = .004), and fewer total symptoms (70.2 ± 16.3 vs 62.3 ± 19.6, P = .03). CONCLUSIONS: Blenderized diets are associated with decreased healthcare use, improved symptom scores, and increased patient satisfaction compared with conventional formulas.

Adjuvant radiotherapy after surgical resection for adrenocortical carcinoma: A systematic review of observational studies and meta-analysis.

PURPOSE: Historically, the role of adjuvant radiotherapy (RT) for patients with adrenocortical carcinoma (ACC) has been controversial. The objective of this research is to review systematically the literature evaluating the role of adjuvant RT in patients with ACC undergone a surgical resection. MATERIALS AND METHODS: The electronic databases were searched for articles published until July 2017 without language restriction: Lilacs, Medline, Embase, and the Cochrane. Two reviewers independently appraised the eligibility criteria and extracted data. When possible, a fixed-effect meta-analysis was done. The systematic review (SR) followed all the criteria of the MOOSE guideline. RESULTS: Overall, 382 citations were identified. After the screening of titles and abstracts, 12 articles (eight case series [48 patients] and 4 cohort studies [136 patients]) were included in the final analysis. For the local recurrence, the pooled relative risk (RR) was RR = 0.46 (95% confidence interval: 0.28-0.75), in favor of adjuvant RT when compared with surgery alone. Concerning overall mortality and disease recurrence, no significant difference between adjuvant RT and surgery was detected, RR = 0.77 (CI 95% 0.49-1.22, P = 0.27), and RR = 0.95 (IC 95% 0.74-1.24, P = 0.67). In all cohort studies, the acute toxicities were graduated as mild and self-limited with nausea and fatigue being the most common symptoms. Only one case (1/50) of impairment of kidney function was detected as late toxicity in these studies. CONCLUSIONS: This SR and meta-analysis indicate that adjuvant RT dramatically reduces the local recurrence of ACC after surgery. Moreover, the treatment has a low acute and late toxicity, resulting in a high therapeutic index. Further, prospective studies are needed to confirm or refute the role of RT on survival and disease recurrence.

INTRODUCTION: Gallbladder cancer is a rare neoplasm, its frequency is variable in the regions of Peru. OBJECTIVE: To determine the frequency and describe the clinical characteristics of gallbladder cancer in southern Peru. METHODS: The reports of the anatomopathological department of the Honorio Delgado Regional Hospital were selected from all samples of cholecystectomies performed between 2009 and 2014 and those that had some result compatible with gallbladder cancer were looked for. Subsequently, the clinical histories were searched to obtain the characteristics of these patients. RESULTS: Of 2991 cholecystectomies, 75 (2.5%) had gall bladder cancer. The most frequent symptom in both groups was pain (96.7%), followed by nausea (87.5%) and vomiting (65.0%). The majority of patients were women (83.3%) older than 60 years (65.0%). The most frequent histological type was the adenocarcinoma (80.0%). CONCLUSION: The frequency of gallbladder cancer in a reference hospital in southern Peru is 2.51%, higher than that reported in other studies in the central and northern regions of Peru.

Pilocarpine and artificial saliva for the treatment of xerostomia and xerophthalmia in Sjögren syndrome: a double-blind randomized controlled trial.

BACKGROUND: Sjögren syndrome (SS) is associated with xerostomia and xerophthalmia. Pilocarpine has been shown to stimulate the secretion of saliva. OBJECTIVES: To investigate and compare the efficacy of pilocarpine and artificial saliva as symptomatic treatments for xerostomia and xerophthalmia in patients with SS. METHODS: A double-blind randomized controlled study was performed. A total of 72 patients with SS were assigned randomly to receive 10 drops of pilocarpine (5 mg) or 10 drops of artificial saliva orally, three times daily for 12 weeks. Whole saliva and tear flow were evaluated at baseline and periodically throughout the study to provide a global assessment of dryness and to report any adverse effects. RESULTS: Patients receiving pilocarpine had a statistically significant improvement in their salivary flow (P < 0·001), lacrimal flow (P < 0·001) and their subjective global assessment (P < 0·001), compared with patients who received artificial saliva. The most common side-effects were sialorrhoea and nausea. CONCLUSIONS: Pilocarpine is more effective than artificial saliva for enhancing salivary and lacrimal secretion in patients with SS. This is the first study to compare the efficacy of pilocarpine and artificial saliva for the treatment of xerostomia and xerophthalmia in SS.

A nationwide study on the prevalence of functional gastrointestinal disorders in school-children / Prevalencia de desórdenes gastrointestinales funcionales en niños. Un estudio a nivel nacional

Abstract: Introduction: Functional gastrointestinal disorders (FGIDs) are highly prevalent worldwide and are thought to result from the interplay of multiple factors that can vary from region to region. Nationwide studies can help understand the regional epidemiology and the pathogenesis of FGIDs. The objectives of this study were to determine the prevalence of FGIDs in school-children of Colombia and assess associated factors. Methods: A cross-sectional study was carried out at twelve private and public schools in ten cities distributed through the four main geographic regions of Colombia. School-children completed a validated questionnaire to assess functional gastrointestinal disorders according to Rome III criteria. Demographic information and past medical and family history was obtained from the parents. Results: A total of 4394/5062 (86.8%) children participated in the study, with ages ranging from 8-18 years (mean = 11.9, SD = 2.3). The percentage of children with al least on FGID was 23.7%. Disorders of defecation were the most common category FGID (11.7%) followed by abdominal pain related-functional gastrointestinal disorders (10.4%). Children have increased odds of FGIDs if they have separated parents (OR 1.22, P=0.007), attend private school (OR 1.54, P<0.001), or have nausea (OR 3.16, P<0.001). Conclusions: This large epidemiological study of pediatric FGIDs is the first to evaluate a broad cross-section of children throughout a nation in the Americas. High prevalence of FGIDs and identified associations with their likelihood are relevant when providing medical care and when planning public health efforts.

Resumen: Introducción: Los desórdenes gastrointestinales funcionales (DGF) son altamente prevalentes a nivel mundial. Se postula que estos desórdenes resultan del interjuego de múltiples factores que pueden variar regionalmente. Estudios a nivel nacional pueden ayudar a comprender la epidemiología regional y la patogénesis de los DGFs. Los objetivos del estudio fueron determinar la prevalencia de DGFs en escolares en Colombia y establecer los factores asociados. Métodos: Estudio de corte transversal realizado en 12 escuelas privadas y públicas en 10 ciudades de las cuatro regiones principales de Colombia. Niños de edad escolar completaron un cuestionario validado para diagnosticar DGFs de acuerdo con los criterios de Roma III. Información demográfica e historia personal y familiar fue obtenida de los padres. Resultados: Un total de 4394/5062 (86.8%) niños participaron en el estudio, rango de edad 8-18 años (promedio = 11.9, desviación estándar (DE) = 2.3). El 23.7% de los niños tuvieron al menos un DGF. Los desórdenes de la defecación fueron los más frecuentes (11.7%), seguidos por desórdenes funcionales de dolor (10.4%). Niños cuyos padres estaban separados (razón de momios (RM) 1.22, p= 0.007), cursaban en escuela privada (RM 1.54, p< 0.001) o reportaban náuseas (RM 3.16, p< 0.001) tuvieron mayor riesgo de DGFs. Conclusiones: Este estudio de DGF es el primero en evaluar un grupo numeroso de niños en diferentes regiones de un país americano. La alta prevalencia de DGFs y la identificación de asociaciones que aumentan el riesgo de desarrollar estos desórdenes son hallazgos relevantes para proveer cuidados médicos y planear estrategias de salud pública.

Dietary counseling adherence during tuberculosis treatment: A longitudinal study.

BACKGROUND: The World Health Organization (WHO) recommends the use of dietary counseling to overcome malnutrition for patients with tuberculosis, with or without HIV, however the response to nutritional treatment depends on patient's adherence to nutritional counseling. OBJECTIVE: Identify the degree of adherence to dietary counseling and predictors of adherence among patients undergoing tuberculosis treatment. DESIGN: Observational prospective follow-up study conducted in adults treating for tuberculosis with or without HIV. Self-reported adherence and 24-h diet recall were checked. Diet counseling according to WHO strategy was offered at each visit for all patients. The endpoint was the adherence to the recommended dietary allowance (RDA) and total calories consumed during tuberculosis treatment. Data were mainly analyzed with marginal models to estimate adjusted trajectories. RESULTS: Sixty-eight patients were included in the study. The maximum probability of total calories consumption of at least one RDA was 80%. The adherence to dietary counseling was low regardless of HIV infection. The negative determinants of adherence were the presence of loss of appetite and nausea/vomiting. For patients with loss of appetite and nausea/vomiting, the probability of total calories consumption of at least one RDA is less than 20% at any time. CONCLUSION: The loss of appetite and nausea/vomiting are highly prevalents and were the main causes of non-adherence to dietary counseling.

Diabetes is Associated with Severe Adverse Events in Multidrug-Resistant Tuberculosis. / La diabetes se asocia con reacciones adversas graves en la tuberculosis multirresistente.

INTRODUCTION: Diabetes mellitus (DM), a very common disease in Mexico, is a well-known risk factor for tuberculosis (TB). However, it is not known by which extent DM predisposes to adverse events (AE) to anti-TB drugs and/or to worse outcomes in patients with multidrug-resistant (MDR-TB) and extensively drug-resistant TB (XDR-TB). The main objective of this study was to describe the outcomes of TB treatment, the impact of DM and the prevalence of AE in a cohort of patients with MDR-/XDR pulmonary TB treated at the national TB referral centre in Mexico City. RESULTS: Ninety patients were enrolled between 2010 and 2015: 73 with MDR-TB (81.1%), 11 with pre-XDR-TB (12.2%) and 6 (6.7%) with XDR-TB, including 49 (54.4%) with DM, and 3 with Human Immunodeficiency Virus (HIV) co-infection (3.3%). In 98% of patients, diagnosis was made by culture and drug susceptibility testing, while in a single case the diagnosis was made by a molecular test. The presence of DM was associated with an increased risk of serious drug-related AEs, such as nephrotoxicity (Odds Ratio [OR]=6.5; 95% Confidence Interval [95% CI]: 1.9-21.8) and hypothyroidism (OR=8.8; 95% CI: 1.8-54.2), but not for a worse outcome. CONCLUSIONS: Our data suggest that DM does not impact second-line TB treatment outcomes, but patients with DM have a higher risk of developing serious AEs to drug-resistant TB treatment, such as nephrotoxicity and hypothyroidism.

[Influence of gender on the clinical presentation and associated diseases in adults with celiac disease]. / Influencia del género en la presentación clínica y enfermedades asociadas en adultos con enfermedad celíaca (EC).

INTRODUCTION: Celiac disease is diagnosed predominantly in women. OBJECTIVES: We investigated the influence of gender on (i) age at diagnosis, (ii) clinical manifestations, and (iii) prevalence of associated disorders. METHODS: Clinical data were abstracted from the medical record of adults with biopsy-proven celiac disease. RESULTS: The cohort consisted of 385 patients (women, 71%). Women were diagnosed at a younger age (women, 46.1 years; men, 52.6 years; p = 0.001). The prevalence of the following symptoms was higher in women: nausea/vomiting (women, 31%; men, 16%; p = 0.001), constipation (women, 21%; men, 10%; p = 0.007), and malaise/fatigue (women, 43%; men, 33%; p = 0.06). Greasy stools were more prevalent in men (women, 11%; men, 22%; p = 0.006). Autoimmune diseases were observed in 127 (33%) patients with a female to male ratio of 1.6 (women, 37%; men, 23%; p = 0.006). Depression, osteoporosis, and fibromyalgia predominated in women. CONCLUSIONS: Our findings suggest clinically relevant gender-related differences in celiac disease. These gender differences should be taken into account when managing adult patients with celiac disease.

High Prevalence of Nausea among School Children in Latin America.

OBJECTIVES: To evaluate the prevalence of nausea and its association with functional gastrointestinal disorders (FGIDs) in a large-scale, population-based study of Latin American school children. STUDY DESIGN: This cross-sectional study collected data from children in 3 Latin American countries. A Spanish version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-III) was administered to school children in Central and South America. Subjects were classified into FGIDs based on Rome criteria (QPGS-III). Students from 4 public and 4 private schools in the countries of El Salvador, Panama, and Ecuador participated in this epidemiologic study. RESULTS: A total of 1137 school children with mean age 11.5 (SD 1.9, range 8-15) years completed the QPGS-III (El Salvador n = 399; Panama n = 321; Ecuador n = 417). Nausea was present in 15.9% of all school children. Two hundred sixty-eight (24%) children met criteria for at least 1 FGID. Nausea was significantly more common in children with FGIDs compared with those without: El Salvador 38% vs 15% (P < .001); Panama 22% vs 7% (P < .001); Ecuador 25% vs 13% (P = .004). Among children with FGIDs, those with functional constipation had a high prevalence of nausea. Nausea was significantly more common in girls and children attending private schools. CONCLUSIONS: Nausea is commonly present in Latin American school children. FGIDs are frequently associated with nausea.

Malignant middle cerebral artery infarction: a clinical study of 32 patients.

BACKGROUND AND OBJECTIVE: Malignant middle cerebral artery infarction is a devastating type of ischemic stroke whose clinical predictors remain scarcely known. The present study aims to improve the knowledge about the prognosis factors through an analysis of a malignant middle cerebral artery infarction sample of patients from our stroke registry. MATERIAL AND METHODS: From a total of 1,396 patients with ischemic stroke in the middle cerebral artery included in the "Sagrat Cor Hospital of Barcelona Stroke Registry", we identified 32 patients with malignant middle cerebral artery infarction (2.3%). Demographic, anamnestic, clinical, and outcome variables in this subgroup of patients were compared with those of the middle cerebral artery. The independent predictive value of each variable on the development of malignant middle cerebral artery infarction was assessed with a logistic regression analysis. RESULTS: The mean age was 74.7 (SD, 11.4) years and 50% were males. In-hospital death was observed in eight patients (25%) and early bad prognosis (in-hospital death or severe residual focality at discharge) was present in 16 patients (50%). Decreased consciousness (OR: 4.17; 95% CI: 2.02-8.61), presence of nausea or vomiting (OR: 3.65; 95% CI: 1.40-8.49), and heavy smoking (> 20 cigarettes/day; OR: 2.62; 95% CI: 1.03-6.64) appeared to be independent prognostic factors for malignant middle cerebral artery infarction in the multivariate analysis. CONCLUSIONS: Malignant middle cerebral artery infarction is an infrequent clinical condition associated with poor prognosis and high mortality rate. In our sample, decreased consciousness, nausea or vomiting, and heavy smoking are the main clinical factors associated.

Nausea, vomiting and quality of life of patients with cancer undergoing antineoplastic treatment: an evaluation by pharmacists.

OBJECTIVE: This study aims to evaluate the frequency and severity of nausea and vomiting using two different instruments and relate them to quality of life (QOL) in patients with cancer receiving antineoplastic treatment. METHODS: Severity of chemotherapy-induced nausea and vomiting (CINV) was measured by Common Terminology Criteria for Adverse Events (CTCAE) and a numerical scale. QOL was assessed using the Functional Assessment of Cancer Therapy-General questionnaire. KEY FINDINGS: Of the 50 patients studied, 60.0% reported nausea (40.0% CTCAE grade 1; 66.7% moderate intensity on numerical scale) and 30.0% reported vomiting (46.7% CTCAE grades 1 and 2, each; 66.7% moderate intensity on numerical scale). CINV did not influence overall QOL. CONCLUSION: The frequency of CINV was high. There was no association between nausea/vomiting and overall QOL.

[Incidence and management of chemotherapy-induced nausea and vomiting in women with breast cancer]. / Ocorrência e manejo de náusea e vômito no tratamento quimioterápico em mulheres com câncer de mama.

The objective of this study was to analyze the incidence of chemotherapy-induced nausea and vomiting in women with breast cancer and identify strategies used by them to control these signs and symptoms. Data for this cross-sectional study were collected through interviews during the last cycle of chemotherapy, between August 2011 and March 2012, in a university hospital in the State of São Paulo. The sample consisted of 22 women between the ages of 31 and 70, of whom 77.3% reported nausea and 50% vomiting during treatment. Regarding symptom management, 82% of the women reported having received some information centered on the use of prescribed medication. However, 27.3% did not know what medication they had taken. We concluded that there is a lack of systematic care and institutional protocol to guide professionals in providing standardized information to women so they can better control nausea and vomiting.
