Bioelectric impedance phase angle is associated with hospital mortality of geriatric patients

Abstract Background Community-acquired pneumonia (CAP) and acute myocardial infarction cardiovascular (AMI) are two important health issues in older patients. Little is known regarding characteristics of AMI in older patients hospitalized for CAP. Therefore, we investigated the prevalence, characteristics compared with younger patients, impact on clinical outcomes and risk factors of AMI during hospitalization for CAP in geriatric patients. Methods Eleven thousand nine adult inpatients consisted of 5111 patients≥65 years and 5898 patients< 65 years in respiratory ward diagnosed with CAP were retrospectively analyzed by electronic medical records. Results 159 (3.1%) older patients in respiratory ward experienced AMI during hospitalization for CAP. AMI were more frequently seen in patients≥65 years compared with patients< 65 years (3.1% vs. 1.0%). Patients≥65 years who experienced AMI during hospitalization for CAP had higher percentage of respiratory failure (P = 0.001), hypertension (P = 0.008), dyspnea (P = 0.046), blood urea nitrogen (BUN) ≥7 mmol/L (P < 0.001), serum sodium< 130 mmol/L (P = 0.005) and had higher in-hospital mortality compared to patients< 65 years (10.1% vs. 6.6%). AMI was associated with increased in-hospital mortality (odds ratio, OR, with 95% confidence interval: 1.49 [1.24–1.82]; P < 0.01). Respiratory failure (OR, 1.34 [1.15–1.54]; P < 0.01), preexisting coronary artery disease (OR, 1.31[1.07–1.59]; P = 0.02), diabetes (OR, 1.26 [1.11–1.42]; P = 0.02) and BUN (OR, 1.23 [1.01–1.49]; P = 0.04) were correlated with the occurrence of AMI in the older patients after hospitalization with CAP. Conclusions The incidence of AMI during CAP hospitalization in geriatric patients is notable and have an impact on in-hospital mortality. Respiratory failure, preexisting coronary artery disease, diabetes and BUN was associated with the occurrence of AMI in the older patients after hospitalization with CAP. Particular attention should be paid to older patients with risk factors for AMI.

Pendahuluan. Bioelectric Impedance Analysis (BIA) mulai banyak digunakan dalam mengevaluasi status nutrisi. Belum ada data penelitian nutrisi di Indonesia yang menggunakan BIA. Penelitian ini dilakukan untuk mengetahui perbedaan rerata hasil pemeriksaan BIA antara status nutrisi baik dan malnutrisi pada penderita penyakit gastrointestinal dan hati yang dirawat inap. Metode. Penelitian potong lintang retrospektif terhadap penderita yang dirawat inap di ruang perawatan interna RSCM periode 1 Juni-31 Desember 2013, untuk mengetahui perbedaan rerata hasil pemeriksaan BIA penderita status nutrisi baik dan malnutrisi pada penyakit gastrointestinal dan hati yang dirawat inap.Hasil. Dari 28 penderita dengan status nutrisi baik, 71,57% laki-laki, dan 21,47% wanita. Dari 28 penderita malnutrisi, 53,60% laki-laki, dan 46,40% wanita. Rerata hasil pemeriksaan BIA antara penderita nutrisi baik dan malnutrisi adalah: lean body mass, 49,5 ± 8,59 v s39,68 ± 6,28kg, p<0,001; body cell mass, 32,19 (20,49-40,95) vs 25,23 (17,83-31,64) kg, p=0,003; total body water, 35,69±1,17 vs 28,58±0,85 kg, p<0,001; dan phase angle 6,18◦(3,73-10,11)◦ vs 3,46◦ (0,40-6,51)◦; , p<0,001. Simpulan. Pada penderita penyakit gastrointestinal dan hati yang dirawat inap dengan status nutrisi baik, memiliki nilai body mass, body cell mass,total body water dan phase angle hasil pemeriksaan BIA yang lebih tinggi dibandingkan dengan penderita malnutrisi.

Introduction: Resection is an optimal way of treatment of hepatic tumors and metastasis from another organ. The operational injury may influence on patients body composition examined by bioelectrical impedance (BIA). Analysis of parameters may be helpful in identifying early changes indicating of deterioration in nutritional status. The aim of the study: was to assess changes in body composition of patients before and after resection of liver tumors and potential radiofrequency ablation of lesions. Material and methods: The study included a group of 50 patients of the Department of General, Gastroenterological and Oncological Surgery, Medical University of Warsaw, who were qualified for radical surgical treatment of tumors within the liver. Data on water content, fat, muscle and cell mass were analyzed. Results: Comparing data obtained from patients before and after intervention in the liver, statistically significant (p <0.05) loss of intracellular water, muscle mass, cell mass, as well as adipose tissue, was demonstrated. The phase angle value in these patients also significantly changed, decreasing by an average of 0.61°. On the other hand, the increase in content was noted in the case of extracellular water. Conclusions: Surgical intervention within the liver causes noticeable, unfavorable changes in the body composition, as evidenced by the reduction in the value of muscle mass, as well as cellular mass, resulting in a decrease in the phase angle. Bioelectric impedance is a suitable method for assessing changes in body composition of patients undergoing liver resection and is useful in clinical practice. It is advisable to conduct further research in the group of patients undergoing invasive treatment of the liver due to: an increasing number of such operations and centers where this type of surgical intervention is performed.
