Purpose: Phase angle (PA) is objectively determined from resistance and reactance measured by bioelectrical impedance analysis (BIA)− a quick, noninvasive method. The aim of this study was to evaluate the clinical application of PA by BIA for nutritional assessment of critically ill patients. Methods: Eighty nine adult patients admitted to a medical intensive care unit (ICU) of a tertiary academic hospital from August 2012 to September 2013 were analyzed. PA values were measured by direct segmental multi-frequency BIA. As traditional …

Background & aims Although initial fluid resuscitation in sepsis is critical for the treatment of tissue hypoperfusion, little evidence supports the distribution of infused fluid in patients with sepsis. This study was designed to assess the body water distribution in patients with sepsis using bioelectrical impedance analysis and correlate the trend in body water distribution during fluid treatment with the prognosis of patients with sepsis. Methods A prospective study in a single emergency department was performed, and adult patients suspected of …

Background The current severe acute respiratory syndrome coronavirus 2 pandemic is unprecedented in its impact. It is essential to shed light on patient characteristics that predispose to a more severe disease course. Obesity, defined as a BMI> 30 kg/m 2, is suggested to be one of these characteristics. However, BMI does not differentiate between fat mass and lean body mass, or the distribution of fat tissue. The aim of the present study was to assess the body composition of COVID-19 patients admitted to the ward or the ICU …

Objective Understanding how best to measure renal function in HIV-infected patients is critical because estimated glomerular filtration rate (eGFR) in HIV-infected patients can be affected by ethnicity and body composition. We validated the available eGFR equations and compared them to the plasma 99m Tc-diethylenetriaminepentaacetic acid (99m Tc-DTPA) clearance in HIV-infected patients. Design

The objective of this study was to identify the association of phase angle with physical fitness in children and adolescents infected with HIV. Sixty‐four children and adolescents infected with HIV (8‐15 years old) were tested for vertical transmission. The electrical bioimpedance was used to obtain the phase angle. Body fat (BF) and lean soft tissue mass (LSTM) were measured by x‐ray absorptiometry, and the manual grip strength was evaluated by dynamometry. The peak oxygen consumption (VO2 peak) was measured by respiratory …

Older adults face physiological, psychological, social, and economic changes, which may impair nutritional status, making the body vulnerable to illness and adverse clinical outcomes. Little is known regarding the nutritional status among elderly people living with HIV (PLHIV). We aimed to study the prevalence of malnutrition and the associated factors in a Thai aging cohort. A cross-sectional study was conducted among PLHIV> 50 years of age on long-term antiretroviral therapy and HIV-negative controls, frequency matched by sex and …

Background: After the World Health Organization's first technical consultation on Nutrient Requirements for People Living with HIV/AIDS in Geneva, 2003, a lot of research questions that are considered crucial for enhancing our understanding of the interaction of nutrition and HIV infection were raised and until this moment, left unanswered. To gain a better understanding of HIV and nutrition, we implemented a comprehensive approach. The aim of our study was to assess the nutritional and metabolic status in order to enhance the …

Presarcopenia and sarcopenia were evaluated in HIV-infected individuals and in healthy elderly controls according to the consensus definitions of the European Working Group on Sarcopenia in Older People. Bioelectrical impedance, a hydraulic hand dynamometer, and gait speed were used to evaluate muscle mass, muscle strength, and physical performance, respectively. Adjusted and unadjusted binary logistic regression predicted the risk of sarcopenia. Predictor contribution was assessed by the Wald test. Significance was …

The purpose of this retrospective case-control study was to investigate the frequency of Apolipoprotein E (ApoE) polymorphisms and their influence on antiretroviral therapy (ART)-induced lipodystrophy or dyslipidemia in HIV-infected Thai patients. The clinical …

Objectives To investigate whether phase angle (PhA) measured by bioelectrical impedance analysis (BIA) and frailty are associated with the outcomes of critical illnesses. Design A single-center prospective cohort study. Setting Medical intensive care unit (ICU) in Seoul National University Hospital, Seoul, Republic of Korea. Participants 97 patients who were admitted to the medical ICU. Measurements On admission, PhA was measured by BIA, and frailty was assessed by the Korean Modified Barthel Index (KMBI) scoring system. Patients …
