The association of hydration status with physical signs, symptoms and survival in advanced cancer-The use of Bioelectrical Impedance Vector Analysis (BIVA) technology to evaluate fluid volume in palliative care: An observational study

Background Hydration in advanced cancer is a controversial area; however, current hydration assessments methods are poorly developed. Bioelectrical impedance vector analysis (BIVA) is an accurate hydration tool; however its application in advanced cancer has not been explored. This study used BIVA to evaluate hydration status in advanced cancer to examine the association of fluid status with symptoms, physical signs, renal biochemical measures and survival. Materials and methods An observational study of 90 adults with advanced cancer receiving care in a UK specialist palliative care inpatient unit was conducted. Hydration status was assessed using BIVA in addition to assessments of symptoms, physical signs, performance status, renal biochemical measures, oral fluid intake and medications. The association of clinical variables with hydration was evaluated using regression analysis. A survival analysis was conducted to examine the influence of hydration status and renal failure. Results The hydration status of participants was normal in 43 (47.8%), 'more hydrated' in 37 (41.1%) and 'less hydrated' in 10 (11.1%). Lower hydration was associated with increased symptom intensity (Beta = -0.29, p = 0.04) and higher scores for physical signs associated with dehydration (Beta = 10.94, p = 0.02). Higher hydration was associated with oedema (Beta = 2.55, p<0.001). Median survival was statistically significantly shorter in 'less hydrated' patients (44 vs. 68 days; p = 0.049) and in pre-renal failure (44 vs. 100 days; p = 0.003). Conclusions In advanced cancer, hydration status was associated with clinical signs and symptoms. Hydration status and pre-renal failure were independent predictors of survival. Further studies can establish the utility of BIVA as a standardised hydration assessment tool and explore its potential research application, in order to inform the clinical management of fluid balance in patients with advanced cancer

Internet-based guided self-help for glioma patients with depressive symptoms: design of a randomized controlled trial

Background: Among glioma patients, depression is estimated to be more prevalent than in both the general population and the cancer patient population. This can have negative consequences for both patients and their primary informal caregivers (e.g., a spouse, family member or close friend). At present, there is no evidence from randomized controlled trials for the effectiveness of psychological treatment for depression in glioma patients. Furthermore, the possibility of delivering mental health care through the internet has not yet been explored in this population. Therefore, a randomized controlled trial is warranted to evaluate the effects of an internet-based, guided self-help intervention for depressive symptoms in glioma patients. Methods/design: The intervention is based on problem-solving therapy. An existing 5-week course is adapted for use by adult glioma patients with mild to moderate depressive symptoms (Center for Epidemiology Studies Depression Scale score ≥12). Sample size calculations yield 126 glioma patients to be included, who are randomly assigned to either the intervention group or a waiting list control group. In addition, we aim to include 63 patients with haematological cancer in a non-central nervous system malignancy control group. Assessments take place at baseline, after 6 and 12 weeks, and after 6 and 12 months. Primary outcome measure is the change in depressive symptoms. Secondary outcome measures include health-related quality of life, fatigue, costs and patient satisfaction. In addition, all patients are asked to assign a primary informal caregiver, who does not participate in the intervention but who is asked to complete similar assessments. Their mood, health-related quality of life and fatigue is evaluated as well. Discussion: This is the first study to evaluate the effects of problem-solving therapy delivered through the internet as treatment for depressive symptoms in glioma patients. If proven effective, this treatment will contribute to the mental health care of glioma patients in clinical practice. Trial registration: Netherlands Trial Register NTR322

Correlação clínico-topográfica em glioblastomas multiformes nas síndromes motoras: significados fisiopatológicos Clinical topographic findings in glioblastoma multiforme and the relation with motor impairment

O glioblastoma multiforme (GBM) é o tumor glial com maior grau de malignidade. Acomete principalmente os hemisférios cerebrais apresentando sintomas e sinais focais ou gerais, relacionados ao tamanho, localização e taxa de crescimento tumoral. OBJETIVO: Analisar a relação do déficit motor com a topografia do GBM. MÉTODO: Foram estudados 43 casos de GBM, referidos quanto à idade, sexo, localização e a síndrome motora. RESULTADOS: O tumor predominou em adultos (média de 55 anos), sexo masculino (55,82%), localização frontal (aproximadamente 40%). A hemiparesia prevaleceu como distúrbio motor, somente não ocorrendo em 2 casos de lesão frontal, 2 temporais, 1 parietal, 1 occipital e 1 fronto-temporal. CONCLUSÃO: Os achados clínico-topográficos favorecem os efeitos infiltrativos (lesões extensas) como responsáveis pela síndrome motora em detrimento aos efeitos compressivos (lesões localizadas).<br>Glioblastoma multiforme (GBM) is the glial tumor with the highest grade of malignity. It mainly affects the cerebral hemispheres, presenting general or focal signs and symptoms, which depend on the size, the location of the lesion and rate of growth of the tumor. OBJECTIVE: To analyze the relationship between motor impairment and GBM topography. METHOD: We studied 43 cases of GBM, related to the age, gender, localization and motor impairment. RESULTS: The occurrence of the tumor was preponderant in adults (mean age 55 years old), men (55.82%), and frontal lobe (approximately 40%). The principal motor impairment was hemiparesis, with the exception of 2 cases in the frontal lobe, 2 temporal, 1 parietal, 1 occipital and 1 frontotemporal. CONCLUSION: The clinical-topographic findings lead to consider the infiltrative effects (broad lesions) are responsible for the motor impairment rather than compressive effects (located lesions)

Factors influencing quality of life in patients with benign primary brain tumors: prior to and following surgery

Goals: Few studies have repeatedly evaluated quality of life and potentially relevant factors in patients with benign primary brain tumor. The purpose of this study was to explore the relationship between the experience of the symptom distress, functional status, depression, and quality of life prior to surgery (T1) and 1 month post-discharge (T2). ---------- Patients and methods: This was a prospective cohort study including 58 patients with benign primary brain tumor in one teaching hospital in the Taipei area of Taiwan. The research instruments included the M.D. Anderson Symptom Inventory, the Functional Independence Measure scale, the Hospital Depression Scale, and the Functional Assessment of Cancer Therapy-Brain.---------- Results: Symptom distress (T1: r=−0.90, p<0.01; T2: r=−0.52, p<0.01), functional status (T1: r=0.56, p<0.01), and depression (T1: r=−0.71, p<0.01) demonstrated a significant relationship with patients' quality of life. Multivariate analysis identified symptom distress (explained 80.2%, Rinc 2=0.802, p=0.001) and depression (explained 5.2%, Rinc 2=0.052, p<0.001) continued to have a significant independent influence on quality of life prior to surgery (T1) after controlling for key demographic and medical variables. Furthermore, only symptom distress (explained 27.1%, Rinc 2=0.271, p=0.001) continued to have a significant independent influence on quality of life at 1 month after discharge (T2).---------- Conclusions: The study highlights the potential importance of a patient's symptom distress on quality of life prior to and following surgery. Health professionals should inquire about symptom distress over time. Specific interventions for symptoms may improve the symptom impact on quality of life. Additional studies should evaluate symptom distress on longer-term quality of life of patients with benign brain tumor
