BACKGROUND: Magnetic resonance imaging-estimated proton-density-fat-fraction (MRI-PDFF) has been shown to be a noninvasive, accurate and reproducible imaging-based biomarker for assessing steatosis and treatment response in nonalcoholic steatohepatitis (NASH) clinical trials. However, there are no data on the magnitude of MRI-PDFF reduction corresponding to histologic response in the setting of a NASH clinical trial. The aim of this study was to quantitatively compare the magnitude of MRI-PDFF reduction between histologic responders versus histologic nonresponders in NASH patients...

BACKGROUND/PURPOSE: The growing demand for a youthful appearance, including a favorable body shape, has motivated recent developments in noninvasive body contouring techniques. Our aim was to investigate the efficacy and safety of a new version of a 4D handpiece-mounted cooling device for cryolipolysis with or without tumescent injections. METHODS: We conducted a side-by-side comparative study using two female porcine models. Two areas of each pig's left abdomen were treated using a conventional device and the new cooling device, and two areas of the right abdomen were also treated using the conventional and new cooling device, but both were combined with tumescent-solution injections...

Recently, a number of modalities have been used for noninvasive fat reduction. Radiofrequency (RF) technology is a promising tool for noninvasive body and face contouring. The aim of this study is to evaluate the efficacy and safety of novel noninvasive RF technology for the reduction of submental fat with 6 months of follow-up. Twenty-one subjects with submental fat accumulation were treated twice at 1-month intervals with monopolar RF, which could also be used to monitor real-time temperature. The submental fat thickness and the circumference were evaluated with ultrasonography and a tape measure, respectively, at baseline followed by 1 and 6 months after the last treatment (0, 2, and 7 months)...

Cryolipolysis is a noninvasive esthetic procedure that utilizes controlled cooling to reduce subcutaneous fat. Clinical studies have established its safety, efficacy, and tolerability for fat reduction in a variety of areas including the abdomen, flanks, thighs, submental area, arms, back, and chest. Because of obvious esthetic concerns, long-term unilateral studies leaving an untreated flank, thigh, or arm are not performed, but serve as ideal controls for weight gain or loss or re-distribution of fat for other reasons...

BACKGROUND: Lipid storage myopathy (LSM) is a genetically heterogeneous group with variable clinical phenotypes. Late-onset multiple acyl-coenzyme A dehydrogenation deficiency (MADD) is a rather common form of LSM in China. Diagnosis and clinical management of it remain challenging, especially without robust muscle biopsy result and genetic detection. As the noninvasion and convenience, muscle magnetic resonance imaging (MRI) is a helpful assistant, diagnostic tool for neuromuscular disorders...

For skin tightening, ablative and nonablative lasers have been used with various parameters full or fractionated. Currently, other energy-based technologies have been developed such as radiofrequency (RF) from mono- to multipolar, microneedling RF, and high-intensity focused ultrasound. They heat up the tissue to a clinical endpoint. Temperatures above 42°C stimulate fibroblasts to produce more collagen and some technologies produce small coagulation points that allow to shrink and to tighten the tissue with less downtime or side effects...

BACKGROUND: Noninvasive body shaping methods seem to be an ascending part of the aesthetics market. As a result, the pressure to develop reliable methods for the collection and presentation of their results has also increased. The most used techniques currently include ultrasound measurements of fat thickness in the treated area, caliper measurements, bioimpedance-based scale measurements or circumferential tape measurements. Although these are the most used techniques, almost all of them have some limitations in reproducibility and/or accuracy...

To date, there have been no objective measurements of subcutaneous volume loss following treatments with a noninvasive radiofrequency (RF)-based device. Twenty female patients were treated with a suction-coupled bipolar RF device using external RF energy combined with pulsed electromagnetic RF energy for subcutaneous fat reduction. Parameters followed included weight, Vectra measurements of abdominal circumference and torso volume, and high-definition ultrasound measurements of fat thickness. Measurements were taken before treatment and three times following treatment...

Noninvasive fat reduction is claimed by many device manufacturers, but proof of efficacy has been difficult to establish. This prospective study was designed to measure the reduction of fat thickness and actual volume reduction in 20 female patients treated with an external radiofrequency (RF) device. This device combines RF heat, suction coupled vacuum, and oscillating electrical pulses that induce adipocyte death over time. Patients underwent pre- and post-treatment and intercurrent measurements of weight, body mass index, ultrasonic transcutaneous fat thickness, and 2D and 3D Vectra photography with independent calculation of circumferential and volumetric change...

Nonalcoholic fatty liver disease (NAFLD) is highly common and potentially serious in children and adolescents. The term NAFLD refers to a spectrum of diseases ranging from accumulation of fat in the liver (simple steatosis or nonalcoholic fatty liver "NAFL") to the potentially progressive form of nonalcoholic steatohepatitis (NASH) characterized by hepatocyte ballooning, inflammation, and often associated with fibrosis. While large prospective longitudinal studies in pediatric NAFLD are still lacking, growing evidence suggests that children with NAFL are at increased risk for cardiometabolic complications, while those with NASH and advance fibrosis are also at risk for significant liver-related morbidity including cirrhosis and its complications...

There are versatile modalities to achieve noninvasive fat reduction, and most of them have proven to be effective for circumferential reduction of local fat tissue, without any serious or permanent adverse effects. However, the follow-up time is short, ranging from 1 to 24 weeks. Most of the patients would like to know how long will its effect last and whether there is long-term side effect or not. The aim of this study was to assess the long-term efficacy and safety of combination therapy of focused ultrasound and radio frequency for noninvasive body contouring...

The drastic reduction in body weight observed in anorexia nervosa (AN) leads to various endocrine changes and consequently to disturbance in thermoregulation mechanisms and body temperature. Thermography allows for a noninvasive diagnosis of the distribution of skin surface temperatures, which is especially important for difficult patients such as women with AN, who are often very sensitive and difficult to treat. The main aim of this study was to measure the mean temperatures (Tmean ) of selected body areas in young women diagnosed with AN and identify those areas where the temperature differences were particularly significant between healthy women and them...

UNLABELLED: Nonalcoholic fatty liver disease (NAFLD) is strongly associated with insulin resistance and metabolic syndrome, which are linked to obesity. The aim of the study was to assess if weight reduction through 12 months of lifestyle intervention and exercise would lead to improvement of steatosis. METHODS: In a prospective observational study 86 overweight subjects (51 men, 35 women) with steatosis were recruited, after excluding other etiologies. Patients were assigned a caloric goal and a daily fat goal...

In clinical practice obesity is primarily diagnosed through the body mass index. In order to characterize patients affected by obesity the use of traditional anthropometric measures appears misleading. Beyond the body mass index, there are overwhelming evidences towards the relevance of a more detailed description of the individual phenotype by characterizing the main body components as free-fat mass, muscle mass, and fat mass. Among the numerous techniques actually available, bioelectrical impedance analysis seems to be the most suitable in a clinical setting because it is simple, inexpensive, noninvasive, and highly reproducible...

BACKGROUND: A reduction in key antioxidants such as glutathione has been noted in brain tissue undergoing oxidative stress in aging and neurodegeneration. To date, no dietary factor has been linked to a higher glutathione concentration. However, in an earlier pilot study, we showed evidence of a positive association between cerebral glutathione and dairy intake. OBJECTIVE: We tested the hypothesis that dairy food consumption is associated with cerebral glutathione concentrations in older adults...
