RESUMO
PURPOSE: This study aimed to investigate the difference in absolute and fat free mass (FFM)-adjusted resting energy expenditure (mREE) and body composition (body weight, fat mass (FM), FFM) between breast cancer survivors (BCs) and controls. Correlations with body composition were analyzed. We examined if survival year, or being metabolically dysfunctional were predictive variables. METHODS: A cross-sectional analysis was conducted on 32 BCs ≤5 years post treatment and 36 healthy controls. Indirect calorimetry measured absolute mREE. Body composition was determined by BOD POD. FFM-adjusted mREE was calculated (mREE/FFM). The Harris-Benedict equation was used to predict REE and determine hyper-/hypometabolism (mREE/pREE). The database of the multidisciplinary breast clinic of the University Hospital of Antwerp was consulted for survival year and metabolic dysfunctions. RESULTS: BCs have similar absolute mREE and greater FFM-adjusted mREE compared to controls. Absolute mREE and body composition between BCs differed; adjusted mREE was similar. FFM correlated significantly with absolute mREE in BCs. A significant interaction term was found between survival year and FM for absolute mREE. CONCLUSION: BCs have similar absolute mREE, but higher FFM-adjusted mREE. Differences in body composition between BCs are suggested to cause inter-individual variations. We suggest that increased FFM-adjusted mREE is caused by metabolic stress related to cancer/treatment. Accurate measurement of REE and body composition is advised when adapting nutritional strategies, especially in patients at risk for developing metabolic dysfunctions.

BACKGROUND: Nutritional support is often based on predicted resting energy expenditure (REE). In patients, predictions seem invalid. Indirect calorimetry is the gold standard for measuring EE. For assessments over longer periods (up to days), room calorimeters are used. Their design makes their use cumbersome, and warrants improvements to increase utility. Current study aims to compare data on momentary EE, obtained by a basic respiration room vs. classical ventilated hood. The objective is to compare results of the basic room and to determine its 1)reliability for measuring EE and 2)sensitivity for minute changes in activity. METHODS: Two protocols (P1; P2)(n = 62; 25 men/37 women) were applied. When measured by hood, participants in both protocols were in complete rest (supine position). When assessed by room, participants in P1 were instructed to stay half-seated while performing light desk work; in P2 participants were in complete rest mimicking hood conditions. The Omnical calorimeter operated both modalities. Following data were collected/calculated: Oxygen uptake ([Formula: see text] O2(ml/min)), carbon dioxide production ([Formula: see text] CO2ml/min), 24h_EE (kcal/min), and respiratory exchange ratio (RER). Statistical analyses were done between modalities and between protocols. The agreement between 24h_EE, [Formula: see text] O2 and [Formula: see text] CO2 obtained by both modalities was investigated by linear regression. Reliability analysis on 24h_EE determined ICC. RESULTS: No significant differences were found for 24h_EE and [Formula: see text] O2. [Formula: see text] CO2 significantly differed in P1 + P2, and P2 (hood > room). RER was significantly different (hood > room) for P1 + P2 and both protocols individually. Reliability of 24h_EE between modalities was high. Modality-specific results were not different between protocols. DISCUSSION/CONCLUSION: The room is valid for assessing momentary EE. Minute changes in activity lead to a non-significant increase in EE and significant increase in RER. The significant difference in [Formula: see text] CO2 for hood might be related to perceived comfort. More research is necessary on determinants of RER, type (intensity) of activity, and restlessness. The design of the room facilitates metabolic measurements in research, with promising results for future clinical use.

PURPOSE: Decongestive lymphatic treatment (DLT) is still the gold standard for treatment of breast cancer-related lymphedema (BCRL). With up to 17% of the patients treated for breast cancer developing BCRL, this morbidity imposes a tremendous financial burden for patients and society. Knowledge about this economic burden related to BCRL and its conservative treatment in a European setting is lacking. The aim of this prospective, longitudinal cohort study was to estimate the direct healthcare costs related to BCRL and its treatment in a European setting. METHODS: Patients with BCRL were treated with DLT consisting of an intensive treatment phase of 3 weeks, followed by a maintenance treatment phase of 6 months. Additionally, the follow-up period comprised 6 months. During these 3 weeks and 12 months, all direct costs associated with the treatment of BCRL and its sequelae were documented through billing prices and a self-developed questionnaire which was administered after the intensive treatment phase, and subsequently 3-monthly during the entire period. RESULTS: A total of 194 patients were enrolled in this study. Of these, 17% (n = 32) showed lymphedema stage I, 56% (n = 109) had lymphedema stage IIa, and 27% (n = 53) had lymphedema stage IIb. Total direct healthcare costs per patient were 2248.93 on average during the entire period of 3 weeks of intensive treatments and 12 months of maintenance decongestive therapy. Within these mean direct costs, 1803.35 (80%) was accounted for statutory health insurances, and 445.58 (20%) was out-of-pocket expenses for patients. CONCLUSION: This study is one of the first standardized high-quality health economic analyses of BRCL treatment in Europe. The present study indicates that the price tag of BCRL treatment in Belgium is high not only for the health insurance but also for the patients Clinical trial registration number The study makes part of a double-blind, multi-center, randomized controlled trial (EFforT-BCRL trial), which is registered in clinicaltrials.gov (NCT02609724).

OBJECTIVES: To provide an overview of costs associated with the treatment of breast cancer-related lymphoedema (BCRL) and its possible sequelae, borne by patients or by society. DATA SOURCES: According to the PRISMA guideline, a systematic literature search was carried out in four electronic databases: PubMed, Web of Science, Cochrane Clinical Trials and EMBASE. Searches were performed on October 1, 2018. STUDY SELECTION: Eligibility criteria: (1) expenses of adults (age > 18 years), (2) concerning patients with BCRL, (3) overview of (in)direct costs associated with BCRL, (4) expenses in which at least one type of conservative treatment modality for lymphoedema is included and/or costs for hospital admissions due to infections. Reviews and meta-analyses were excluded. DATA EXTRACTION: After assessing the risk of bias and level of evidence, quantitative data on (in)direct costs for BCRL treatment during a well-mentioned timeframe were extracted. DATA SYNTHESIS: Eight studies were included. Three studies reported on patient-borne costs related to BCRL. Mean direct costs per year borne by patients ranged between USD$2306 and USD$2574. Indirect costs borne by patients ranged between USD$3325 and USD$5545 per year. Five studies estimated society-borne costs related to BCRL from claims data, billing prices and providers' services during 12 to 24 months of follow-up. Mean direct treatment costs after 1 year of decongestive lymphatic therapy (DLT) ranged between 799 (= USD$1126.60) and USD$3165. CONCLUSION: This systematic review revealed that BCRL imposes a substantial economic burden on patients and society. However, more standardized high-quality health economic analyses among this field are required. Recent economic analyses related to BCRL treatment in Europe, Asia, Africa and South America are lacking. Worldwide, further scrutiny of the economic impact of DLT for BCRL in clinical settings is needed. CLINICAL TRIAL REGISTRATION NUMBER: The review makes part of a double-blind, multi-center, randomized controlled trial (EFforT-BCRL trial), which is registered in clinicaltrials.gov (NCT02609724). CME reference S58689, EudraCT Number 2015-004822-33.

PURPOSE: Breast cancer survivors face a high risk of developing breast cancer-related lymphedema (BCRL). Besides physical symptoms such as swelling, BCRL can have a psychosocial impact and lead to problems in daily functioning. Understanding contributing variables to problems in functioning yields possibilities to improve treatment modalities and consequently patients' quality of life. Therefore, the aim of this study was to explore the association between patient-, lymphedema-, and cancer treatment-related variables with problems in functioning in patients with BCRL. METHODS: A cross-sectional study was performed in 185 patients with BCRL. Problems in daily functioning (dependent variable) were evaluated with the Lymph-ICF-UL questionnaire. Following independent variables were analysed by bi-variate and multivariable analyses, including a stepwise regression analysis: patient-related variables (age, BMI, physical activity level, education), lymphedema-related variables (excessive arm volume, duration of lymphedema, total pitting score, presence of hand edema, hardness of the tissue, lymphedema stage), and cancer treatment-related variables (type of surgery, surgery at the dominant side, radiotherapy, chemotherapy, hormone therapy, immunotherapy, TNM-classification). RESULTS: The Lymph-ICF-UL mean total score was 38% (± 21), representing a moderate amount of problems in general functioning. Multivariable regression analyses revealed that lower physical activity level and lower age are contributing factors to more problems in daily functioning. Stepwise regression analysis indicated that up to 8% of the variance in problems in functioning could be explained by physical activity level and age of patients with BCRL. CONCLUSION: Especially patients with low physical activity level and younger patients experience more problems in functioning. For the determination of certain causal interactions, future longitudinal studies including other independent variables that might explain a higher amount of problems in functioning in this population, are warranted. TRIAL REGISTRATION: The study makes part of a double-blind, multi-center, randomized controlled trial (EFforT-BCRL trial), which is registered in clinicaltrials.gov (NCT02609724). CME reference S58689, EudraCT Number 2015-004822-33.

PURPOSE: To develop a diagnostic tool, the Breast Edema Questionnaire (BrEQ) and to determine its clinimetric properties. METHODS: The BrEQ was developed based on information from literature, experts and breast edema patients. Content validity, construct validity, test-retest reliability, internal consistency and cut-off point were investigated in a group of breast cancer patients. Construct validity made up two parts; convergent and known-groups validity. Convergent validity was tested by correlating the BrEQ with skin thickness measured with ultrasound (US). RESULTS: In part 1 of the BrEQ, symptoms of breast edema were scored from 0 to 10: pain, heaviness, swelling, tensed skin, redness, pitting sign, enlarged skin pores and hardness. Taking into account the International Classification of Functioning, Disability and Health, several activity limitations and participation restrictions were scored from 0 to 10 in part 2. Clinimetric properties of part 1 were examined in 55 patients. US showed that 35 women had breast edema. Content validity was good. Regarding convergent validity, all breast symptoms correlated moderately with skin thickness. The total symptom score had a strong correlation with skin thickness. Concerning known-groups validity, patients with breast edema had a higher total symptom score. Test-retest reliability ranged between moderate and strong. The internal consistency was good for all items and the total symptom score. We identified that a score cut-off point of ≥ 8.5 discriminates between patients with breast edema and those without. CONCLUSION: Part 1 of the BrEQ-Dutch version is a valid and reliable tool for assessing clinical indicators of breast edema.

Objective. Infective endocarditis (IE) is a potentially short-term lethal condition. An association with malignancy could complicate diagnostic and therapeutic decisions. The questions to be answered are: (1) which type of malignancies are encountered; (2) how often has the association between malignancy and IE been described, and (3) what are thus far the diagnostic and treatment strategies for patients with both conditions. Methods. A literature search from 2010 to 2018 has been performed with the focus on IE and cancer/malignancy/neoplasm, as well as with risk factors for adverse outcome, when cancer was included in the analysis. Results. An association between digestive, respiratory and hematologic malignancy with IE has been observed in four large databases. The most important mechanisms for this association are a "port of entry" and immune suppression. Sixteen studies dealt with the effect of short and mid-term cancer on the outcome of surgery of IE in these patients. No uniform management strategy could be identified. It seems that a malignancy does not alter the short-term outcome for IE, although referral to a tertiary cardiac center and surgical treatment are less common for patients with known malignancy. Conclusions. Although there is an association between malignancy and IE, no treatment strategy has yet been developed for these patients. Short-term outcome of IE is unaltered by cancer. In most papers, the effect of cancer on mid-term survival is only significant in a univariate analysis, without being a predictor. The results indicate that cardiac surgery for IE should not be withheld in patients in whom a treatable malignancy has been found.

OBJECTIVES: The primary purpose of this systematic review is to structure the available evidence concerning physical exercise programs and their effects on (1) physical performance outcomes, (2) experienced fatigue, and (3) quality of life (QoL) in patients during the initial treatment for breast cancer. DATA SOURCES: A systematic literature search, based upon the PRISMA guideline, up to January 1, 2018, was performed using four databases (Web of Science, Cochrane Library for Clinical Trials, PubMed, and Medline). STUDY SELECTION: Inclusion criteria were as follows: (1) adults > 18 years; (2) patients with breast cancer undergoing initial treatment; (3) interventions with the aim to influence the patient's physical activity, QoL, or fatigue; (4) randomized controlled trials (RCTs) of all ages. The selected studies were scored for methodological quality, and data concerning physical performance, QoL, and fatigue were extracted. Twenty-eight RCTs were included. DATA EXTRACTION: Different treatment modalities during initial treatment were identified (radiation therapy, chemotherapy, and combination therapy), as well as different types of physical training interventions (cardiovascular endurance exercise, strengthening programs, or a combination of both). Therefore, the results were clustered with regard to the above-mentioned grouping; extracting every relevant outcome related to physical performance (6 MWT or VO2peak; grip/muscle strength), QoL (questionnaires), and fatigue (questionnaires). DATA SYNTHESIS: Different training programs (endurance, resistance, or a combination of both) were found. These programs were applied during different phases of initial treatment. Some programs were supervised while others were home based. Overall, most training interventions provided an improvement in physical performance and a decrease in perceived fatigue. QoL was the outcome variable least susceptible to improvement. CONCLUSION: Different types of exercise programs are available for rehabilitation purposes of breast cancer patients during adjuvant therapy. Overall resistance training or resistance training in combination with CV endurance training provides the best results, especially on physical performance and perceived fatigue.

OBJECTIVE: Morbidity after sentinel lymph node biopsy is often underestimated. The aim of this study was to inventory arm and shoulder complaints in sentinel node-negative breast cancer patients post-surgery after long-term follow-up. METHODS: Sentinel node-negative breast cancer patients with at least 2 years of follow-up after surgery were included in this study. Self-reported arm and shoulder morbidities were assessed using a survey. Patients (n = 126) were asked if they ever developed complaints, if these complaints were still present and whether they were ever treated for these complaints. RESULTS: After a mean follow-up of 55.5 months (range 25-86 months), the prevalence of the self-reported arm and shoulder complaints was 25.8% for pain, 12.0% for numbness, 6.4% for paraesthesias, 7.1% for lymphedema, 8.0% for axillary web syndrome, 26.2% for loss of strength and 19.5% for limitations in range of motion. About 38.1% of the patients were treated by a physical therapist concerning the experienced complaints after SLNB. CONCLUSION: Up to 7 years post-surgery a considerable amount of sentinel node-negative patients still suffer from arm and shoulder complaints. These complaints affect the activities of daily living. Therefore, more research is needed regarding the value of early detection and treatment of these complaints.

OBJECTIVE: To investigate the reliability, time efficiency and clinical feasibility of five commonly used methods for assessing excessive arm volume in patients with breast cancer-related lymphoedema (BCRL). DESIGN: Cross-sectional study. SETTING: University Hospitals Leuven, Belgium. SUBJECTS: 30 participants with unilateral BCRL. METHODS: Excessive arm volume was determined by five different methods: traditional volumetry with overflow, volumetry without overflow, inverse volumetry, optoelectronic volumetry and calculated volume based on circumference measurements. To investigate intra- and inter-rater reliability, measurements were performed twice by the same assessor and once by a different assessor. Intraclass correlation coefficients (ICCs), standard errors of the measurement (SEMs) and systematic changes between the means were calculated. To determine time efficiency, the mean setup time, execution time and total time were examined for each method. Furthermore, 12 limitations regarding clinical feasibility were listed and scored for each method. Finally, an overall ranking score was determined between the methods. RESULTS: Mean age was 65 (±8) years and mean body mass index was 28 (±4) kg/m2. Intra- and inter-rater reliability ranged between strong and very strong. Calculated arm volume based on circumferences (mean excessive arm volume: assessor A: 477 (±367) mL; assessor B: 470 (±367) mL; assessor A (second time): 493 (±362) mL) showed the highest intra- and inter-rater ICCs of .987 and .984, respectively. Optoelectronic volumetry was the fastest method, representing a mean total time of 1 minute and 43 (±26) seconds for performing a bilateral measurement. The least limitations were reported on the calculated volume based on the circumference method (3 out of 12 limitations). CONCLUSION: Calculated volume based on arm circumferences is the best measurement method for evaluating excessive arm volume over time in terms of reliability, low error rate, low cost, few limitations and the time spent.

The aim of the present study was to evaluate the effects of compression bandages, sleeves, intermittent pneumatic compression (IPC) and active exercise on the reduction of breast cancer-related lymphoedema (BCRL). A systematic literature search up to the year January 2016 was performed in CINAHL, Cochrane Register of Controlled Trials, Embase, International Clinical Trials Registry Platform (WHO), PEDro and PubMed. Inclusion criteria were (1) RCTs, (2) reported adequate statistics for meta-analysis, (3) English or German language. Exclusion criteria were (1) effects of drugs, hormonal, radiation and surgical procedures, (2) studies with children, (3) non-breast cancers, lower extremity oedema, (4) impact on fatigue only, diets or sexually transmitted diseases, (5) cost-analysis only and (6) non-carcinogenic syndromes or (7) prevention of breast cancer. After scoring the methodological quality of the selected studies, data concerning volume reduction of the oedema swelling were extracted. Thirty-two studies were included in this systematic review. Nine studies were selected for the RCT-based studies and 19 studies were included in the pre-post studies-based random-effects meta-analyses. All conclusions should be taken with precautions because of the insufficient quality of the selected papers. Exercise seems beneficial in reducing oedema volume in BCRL. IPC seems beneficial in helping to reduce the oedema volume in the acute phase of treatment. Compression sleeves do not aid in the volume reduction in the acute phase; however, they do prevent additional swelling.

OBJECTIVE: To systematically assess the incidence/prevalence and time path of lymphedema in patients with sentinel node-negative breast cancer. DATA SOURCES: A systematic literature search up to November 2013 was performed using 4 different electronic databases: PubMed, Embase, Cochrane Clinical Trials, and Web of Science. STUDY SELECTION: Inclusion criteria were as follows: (1) research studies that included breast cancer patients who were surgically treated using the sentinel lymph node biopsy (SLNB) technique; (2) sentinel node-negative patients; (3) studies that investigated lymphedema as a primary or secondary outcome; (4) data extraction for the incidence or time path of lymphedema was possible; and (5) publication date starting from January 1, 2001. Exclusion criteria were as follows: (1) reviews or case studies; (2) patients who had an SLNB followed by an axillary lymph node dissection (ALND); (3) results of ALND patients and SLNB patients not described separately; and (4) studies not written in English. DATA EXTRACTION: After scoring the methodological quality of the selected studies, the crude data concerning the incidence of lymphedema were extracted. Data concerning the time points and the incidence of lymphedema were also extracted. DATA SYNTHESIS: Twenty-eight articles were included, representing 9588 SLNB-negative patients. The overall incidence of lymphedema in patients with sentinel node-negative breast cancer ranged from 0% to 63.4%. The studies that have assessed lymphedema at predefined time points, instead of a mean follow-up time, demonstrated an incidence range at ≤3, 6, 12, 18, or >18 months postsurgery of 3.2% to 5%, 2% to 10%, 3% to 63.4%, 6.6% to 7%, and 6.9% to 8.2%, respectively. CONCLUSIONS: In SLNB patients, lymphedema is still a problem, mostly occurring 6 to 12 months after surgery. Because of different assessments and criteria, there is a wide range in incidence. Clear definitions of lymphedema are absolutely necessary to tailor therapy.

The purpose of this study was to assess which shoulder and arm impairments are common in sentinel node-negative breast cancer patients and to describe the incidence and time course of these impairments. A systematic literature search was performed using different electronic databases until October 2013. Inclusion criteria were (1) research studies that included breast cancer patients surgically treated using the sentinel lymph node biopsy (SLNB) technique, (2) sentinel node-negative patients, and (3) studies that investigated morbidities of shoulder and/or arm. The exclusion criteria were (1) reviews or case studies, (2) patients who have had a SLNB followed by an axillary lymph node dissection (ALND), (3) results of ALND patients and SLNB patients were not described separately, and (4) no follow-up described. Thirty articles were included, representing 5,448 patients. Shoulder and arm impairments among sentinel node-negative patients are loss of mobility, loss of strength, pain, axillary web syndrome, and sensory disorders. Within the first month after SLNB, the morbidities with the highest incidence are decreased abduction (range 40.8-100 %), forward flexion of the shoulder (range 37-100 %), pain (range 3.4-56.6 %), and numbness (range 2-64 %). Morbidities with the highest incidence after 2 years are pain (range 5.6-51.1 %), numbness (range 5.1-51.1 %), loss of strength (range 0-57.7 %), decreased internal rotation (44.4 %), and decreased abduction (range 0-41.4 %). In conclusion, although the shoulder and arm impairments are less common after SLNB alone compared to ALND, they cannot be neglected. A considerable amount of patients still suffer from those impairments more than 2 years after surgery.

Breast-conserving surgery (BCS) is commonly used in breast cancer treatment. Despite its benefits, some women will be troubled by breast edema. Breast edema may cause an unsatisfactory cosmetic result, influencing the quality of life. The purpose of this systematic review is to investigate the incidence of breast edema and to identify risk factors of breast edema in breast cancer patients following BCS and radiotherapy. A systematic literature search was performed using different electronic databases (PubMed, Web of Science, Cochrane, Embase) until June 2014. Inclusion criteria were as follows: (1) research studies that included female breast cancer patients who were treated with BCS and radiotherapy and (2) studies that investigated the incidence of breast edema and/or risk factors of breast edema. Exclusion criteria were (1) reviews or case studies and (2) studies published before 1995. We identified in total 28 papers which represented 4,011 patients. There was a great variation in the incidence of breast edema (0-90.4 %). We identified several possible risk factors for breast edema namely increasing irradiated breast volume, increasing boost volume, the use of a photon boost, increasing breast separation, a higher density of the breast tissue, a large tumor, a higher specimen weight, postoperative infection, acute postoperative toxicity, and diabetes mellitus. However, their prognostic value remains uncertain. Breast edema is a common complaint after BCS and radiotherapy. A number of possible risk factors associated with breast edema were identified, but further research is warranted.

RESUMO
BACKGROUND: Breast cancer (BC) is the most prevalent tumor in women. Improvements in treatment led to declined mortality, resulting in more survivors living with cancer- or therapy-induced comorbidities. In this study, we investigated the impact of neoplasia and chemotherapy on resting energy expenditure (REE) and body composition, in relation to cancer-related fatigue. Inflammatory parameters were checked as possible explanation for changes in REE. METHODS: Fifty-six women participated: 20 women with BC and 36 healthy controls. Patients were assessed at baseline (T0) and follow-up (T1) after 12 weeks of chemotherapy. Controls were measured once. REE was assessed with indirect calorimetry: body composition (body weight, fat mass, fat-free mass) by air plethysmography. The multidimensional fatigue index (MFI-20) was used to analyze fatigue. Baseline measurements of patients were compared to results of the healthy controls with the independent-samples T-test. The paired-samples T-test investigated the effects of chemotherapy from T0 to T1. A Pearson correlation analysis was conducted between REE, body composition, and fatigue and between REE, body composition, and inflammatory parameters. A linear regression analysis was fitted to estimate the contribution of the significantly correlated parameters. The measured REE at T0 and T1 was compared to the predicted REE to analyze the clinical use of the latter. RESULTS: At baseline, patients with BC had significantly higher REE in the absence of differences in body composition. From baseline to T1, REE and body weight did not change. In contrast, fat-free mass declined significantly with concordant increase in fat mass. Fatigue deteriorated significantly. C-reactive protein at baseline predicted the change in energy expenditure. Predicted REE significantly underestimated measured REE. CONCLUSIONS: Women with BC have higher REE in the tumor-bearing state compared to healthy controls. Chemotherapy does not affect REE but alters body composition. Predictive equations are invalid in the BC population. Results of our study can be used to implement personalized nutritional interventions to support energy expenditure and body composition and minimize long-term comorbidities.
RESUMO
BACKGROUND: Lateropulsion with active Pushing (LwP) is characterized by impairments in postural control. Previous research suggests an association between LwP, lesion location and verticality misperception. This first-ever systematic review evaluates the association between LwP, lesion location and the perception of verticality (PROSPERO: CRD42020159248). METHODS: PubMed, Web of Science, REHABDATA, Embase, Cochrane Library and PEDro were systematically searched on December 16, 2021. Studies were included when examining lesion location or perception of verticality (Subjective Haptic, Visual or Postural Vertical) in supratentorial stroke patients showing LwP. Two reviewers independently screened and assessed risk of bias using the Newcastle Ottawa Scale. Data were qualitatively analyzed and extracted. RESULTS: Nineteen studies were included, examining a total of 340 LwP patients. Lesions in: the thalamus, internal capsule, inferior parietal lobule at the junction of the postcentral gyrus, the posterior insula and the superior temporal gyrus, were associated with LwP. Whereas all studies examining the Subjective Postural and Haptic Vertical (haptic only examined once) reported a significant increased deviation in LwP patients, inconsistent results were found for the Subjective Visual Vertical. Furthermore, the Subjective Visual and Postural Vertical showed inconsistent results for magnitude, direction and variability of this deviation. DISCUSSION: A complex brain network, rather than only one brain region, seems responsible for body control with respect to gravity. A disruption within this network might lead to a bias in the construction of a correct internal reference frame, crucial for perceiving verticality. There was an association of LwP with verticality misperception in all three modalities.

OBJECTIVES: Despite the impact of muscle wasting after burn, tools to quantify muscle wasting are lacking. This multi-centre study examined the utility of ultrasound to measure muscle mass in acute burn patients comparing different methodologies. METHODS: B-mode ultrasound was used by two raters to determine feasibility and inter-rater reliability in twenty burned adults following admission. Quadriceps muscle layer thickness (QMLT) and rectus femoris cross-sectional area (RF-CSA) were measured, comparing the use of i) a single versus average measurements, ii) a proximal versus distal location for QMLT, and iii) a maximum- versus no-compression technique for QMLT. RESULTS: Analysis of twenty burned adults (50 years [95%CI 42-57], 32%TBSA [95%CI 23-40]) yielded ICCs of> 0.97 for QMLT (for either location and compression technique) and> 0.95 for RF-CSA, using average measurements. Relative minimal detectable changes were smaller using no-compression than maximum-compression (6.5% vs. 15%). Using no-compression to measure QMLT was deemed feasible for both proximal and distal locations (94% and 96% of attempted measurements). In 9.5% of cases maximum-compression was not feasible. 95% of RF-CSA measurements were successfully completed. CONCLUSION: Ultrasound provides feasible and reliable values of quadriceps muscle architecture that can be adapted to clinical scenarios commonly encountered in acute burn settings.

After a severe burn injury, a systemic stress response activates metabolic and inflammatory derangements that, among other, leads to muscle mass loss (muscle wasting). These negative effects on skeletal muscle continue for several months or years and are aggravated by short-term and long-term disuse. The dynamic balance between muscle protein synthesis and muscle protein breakdown (proteolysis) is regulated by complex signalling pathways that leads to an overall negative protein balance in skeletal muscle after a burn injury. Research concerning these molecular mechanisms is still scarce and inconclusive, understanding of which, if any, molecular mechanisms contribute to muscle wasting is of fundamental importance in designing of therapeutic interventions for burn patients as well. This review not only summarizes our present knowledge of the molecular mechanisms that underpin muscle protein balance but also summarizes the effects of exercise on muscle wasting post-burn as promising strategy to counteract the detrimental effects on skeletal muscle. Future research focusing on the pathways causing post-burn muscle wasting and the different effects of exercise on them is needed to confirm this hypothesis and to lay the foundation of therapeutic strategies.
