IntroductionMonitoring patient with anorexia nervosa (AN) include clinical, biological and psychological factors. In recent years many researchers criticize the BMI as useful measure for controlling evolution of AN.ObjectivesBioelectrical impedance analysis (BIA) is one of the main methods for nutritional status assessment.AimsThe aim of this study was the assessment of the nutrition status in a group of patients with anorexia nervosa in comparison to healthy population (HP).MethodsThe study involved 37 participants: 21 patients with AN and 16 healthy volunteers constituting the control group (HP). The patients were divided into two groups according a BMI: I group 14 < BMI < 15,5 (n = 11; age 18.0 ± 4.37) and II group: 15,5 < BMI < 17,5 (n = 10; age 17.82 ± 3.68). The mean age of HP was 17.68 ± 1.57 and BMI 20.56 ± 1.16 kg/m2. BIA was performed by using ImpediMed bioimpedance analysis SFB7 BioImp. The parameters: phase angle (PA), TBW%, ECW, ICW, ECW/ICW were analyzed.ResultsPA was decreased significantly in the I (4.5°±0,6) and II group (4.7°±0,6) of AN patients’ in comparison with HP (5.6°±0,7). TBW was 9% higher in I group and ECW was increased 6% in the both AN groups compared with HP (P < 0.01). Additionally ECW/ICW ratio indicated the higher transfer of water into the extracellular compartment in AN group (P < 0.01).ConclusionsBIA is accurate tool to indicate the valuable indicators of detecting malnutrition in AN. Further studies are needed to validate the significance of these parameters for the full identification of the nutrition status of AN patients’.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Status Assessment

Background and Objectives: Body mass index (BMI) is still the only recommended measurable nutritional status assessment parameter in anorexia nervosa (AN). The aim of this study was to measure other anthropometrical and bioelectrical impedance analysis (BIA) parameters in AN patients and to evaluate their nutritional status assessment value. Materials and Methods: The 46 AN female patients were examined at the beginning of hospitalization and followed-up in three measurements (in 6 ± 2 weeks’ intervals). Anthropometrical assessment was based on BMI, circumferences of arm, calf, thigh, hips, waist, their ratio (waist-to-hip ratio (WHR)), and a skinfold test over biceps and triceps muscle, under the scapula, over the hip, and 2 cm from the umbilicus. The BIA parameters included phase angle (PA), membrane capacitance (Cm), and impedance at 200 kHz, and a 5 kHz ratio (Z200/5). Results: In the 1st measurement, BMI correlated with all anthropometric and BIA parameters (p < 0.05). For BIA parameters, the correlation included arm circumference and WHR (p < 0.05). In the follow-up, significant changes were observed in BMI and all BIA parameters. The correlation between BMI and all BIA parameters was present in the 2nd and 3rd measurements (p < 0.05). In the 4th measurement, BMI correlated only with Cm (p = 0.0114). Comparison of BIA parameters according to the state of starvation (BMI < 16.0 kg/m2) revealed that all studied BIA parameters were characterized by statistically significant sensitivity and specificity in the detection of this condition (p < 0.05), except PA in the 4th measurement (p = 0.2099). Conclusions: Selected BIA and anthropometrical parameters could be used for AN patients’ assessment. The study confirmed dynamic changes of BIA parameters during the follow-up. They could be useful in the detection of the state of starvation.

Inguinofemoral Lymphadenectomy

BackgroundLower-limb lymphedema is one of the most disabling adverse effects of vulvar cancer surgery. Multifrequency Bioelectrical Impedance Analysis (MFBIA) is a modern noninvasive method to detect lymphedema. The first aim of this study was to prospectively determine the prevalence of secondary lower-limb lymphedema after surgical treatment for vulvar cancer using objective methods, circumference measurements and MFBIA technique. The second aim was to compare quality of life (QoL) before and 6 months after vulvar surgery.MethodsTwenty-nine patients underwent vulvar cancer surgery in our study: 17 underwent inguinofemoral lymphadenectomy (RAD), and 12 underwent sentinel lymph node biopsy (CONS). Patients were examined before and 6 months after vulvar surgery by measuring the circumference of the lower limbs and with MFBIA. A control group of 27 healthy women was also measured. To evaluate QoL, the European Organisation for Research and Treatment of Cancer (EORTC) QoL questionnaires (QLQ-C30 and QLQ-CX24) were administered to patients before and 6 months after surgery.ResultsUsing circumference measurement, 9 lymphedemas (31%) were diagnosed: 3 (25%) in the CONS and 6 (37.5%) in the RAD group (P= 0.69). After vulvar surgery, patients in the RAD group reported more fatigue and worsening of physical and role functioning. When comparing both groups, the RAD group had significantly worse parameters in social functioning, fatigue, and dyspnea.ConclusionsLower radicality in inguinofemoral lymphadenectomy shows a trend toward lower morbidity and significantly improves QoL. Multifrequency Bioelectrical Impedance Analysis was tested in these patients as a noninvasive, objective method for lymphedema detection. Detection of lymphedema based on subjective evaluations proved to have an unsatisfactory sensitivity. Less radical surgery showed objectively better results in QoL.

Abstract Background The aim of the present study was to test the body composition changes of patients undergoing elective craniotomy using bioelectrical impedance analysis, so as to evaluate the effect of enhanced recovery after surgery (ERAS) to nutritional status of patients. Methods 140 patients who needed elective craniotomy were randomly divided into two groups: observation group (ERAS group) and control group (traditional treatment group). The age was 45.6 ± 12.7 years old. Patients in ERAS group were treated with a set of enhanced recovery measures, while control group patients underwent conventional treatment. Bioelectrical impedance analysis was used to test body composition before and after the surgery. Results The body mass (BM), body mass index (BMI), fat mass (FM), muscle mass (MM), fat mass index (FMI), free-fat mass index (FFMI), body cell mass (BCM), body cell mass index (BCMI), in both groups were decreased after surgery. The decrease of FM and FMI in the control group was significantly different from that in the observation group (p<0.05). However, the decrease of BM, BMI, MM, FFMI, BCM and BCMI in both groups were not statistically significant. Conclusion Patients undergoing elective craniotomy showed various degrees of nutritional injuries, and ERAS could alleviate nutritional injuries caused by operation.
