Background Processed lipoaspirate grafting describes several techniques theorized to leverage the inflammatory and regenerative capacities of mechanically processed adipocytes to rejuvenate and correct skin pathology. While lipoaspirate grafting is typically leveraged to fill visible defects such as depressed scars and dermal lines, additional fat processing allows grafts to stimulate mechanisms of wound healing, including the promotion of fibroblast activation, neovascularization, and neocollagenesis. Objectives This study intends to assess the efficacy and tolerability of processed lipoaspirate grafting monotherapy to improve the clinical appearance of atrophic acne scars. Methods Subjects underwent a single autologous processed lipoaspirate grafting procedure at the site of atrophic acne scars. Objective and subjective scar analysis was performed at 3- and 6-months post-treatment. Scars were assessed via standard photography, topographic analysis, and noninvasive skin measurements. In addition, microbiopsies were obtained before and after treatment to assess histological or genetic changes. Clinical improvement was assessed using Subject and Clinician Global Aesthetic Improvement Scales (GAIS) and blinded photographic evaluation. Results Ten subjects between ages 18 and 60 completed the study. Clinical evaluation demonstrated that fat grafting improved the appearance of atrophic acne scars. CGAIS and SGAIS score showed clinical improvement at both 3- and 6-month follow-up compared to baseline (p Conclusions Micronized lipoaspirate injection is a viable and effective option to improve the appearance of facial acne scarring. Favorable improvements in atrophic acne scarring were captured by objective analysis of skin ultrastructure as well as improvement in subjective assessments of scarring.

Intense pulsed light (IPL) is a noninvasive therapeutic option to treat benign pigmented lesions by targeting melanin.The purpose of this study was to assess IPL as a treatment for benign pigmented dorsal hand lesions.A total of fifteen subjects, 40 to 73 years old, received 3 monthly IPL treatments over the dorsal hands. Subjects followed up 1 and 3 months after treatment. At every visit, photographs were taken using the VISIA Complexion Analysis System (Canfield Scientific, Fairfield, NJ) and analyzed using the RBX Brown Spots Analysis algorithm. The Clinician Global Aesthetic Improvement Scale and Subject Global Aesthetic Improvement Scale were completed at both follow-up visits.A total of fifteen subjects completed all six visits. The number of brown spots decreased 9.26% ( p = .0004) and 7.52% ( p = .0132) at each follow-up visit. The mean brown intensity decreased 6.15% ( p = .0183) and 7.67% ( p = .0178), whereas the mean contrast intensity decreased 8.88% ( p.0001) and 6.60% ( p = .0007) 1 and 3 months after treatment, respectively. The mean Clinician Global Aesthetic Improvement Scale was 2.03 and 2.23, whereas the mean Subject Global Aesthetic Improvement Scale 1 and 3 months after treatment was 1.6 and 1.8, respectively.Objective analysis, along with clinician and subject assessments, showed an improvement in the appearance of benign pigmented lesions in the treated area after 3 IPL treatments.

Background Although ablative techniques are the standard of care for the treatment of fine lines and wrinkles, microneedling offers a minimally invasive alternative. Objectives The purpose of this study was to assess the efficacy of microneedling on facial and neck fine lines and wrinkles. Methods Thirty-five subjects between 44 and 65 years old with Fitzpatrick skin types I to IV received 4 monthly microneedling treatments over the face and neck. Subjects returned 1 and 3 months posttreatment. At every visit, high-resolution ultrasonography and optical coherence tomography were performed, and transepidermal water loss and skin elasticity were measured. Microbiopsies (0.33 mm) were collected pretreatment, before the fourth treatment and 3 months posttreatment. Results Thirty-two subjects (30 females, 2 males) completed all 7 visits. Facial dermal and epidermal density increased 101.86% and 19.28%, respectively, from baseline at 3 months posttreatment. Facial elasticity increased 28.2% from baseline at 3 months posttreatment. Facial attenuation coefficient increased 15.65% and 17.33% at 1 and 3 months posttreatment, respectively. At study completion, blood flow at a depth of 300 µm decreased 25.8% in the face and 42.3% in the neck. Relative collagen type III and elastin gene expression was statistically higher 3 months posttreatment. However, total elastin protein levels were unchanged from baseline values. Dermal muscle formation was observed in 58% of biopsies extracted 3 months posttreatment compared with 15.3% at baseline. Conclusions The results illustrate the effects of microneedling treatments. Noninvasive measurements and biopsy data showed changes in skin architecture and collagen/elastin gene expression, suggesting skin rejuvenation, with new extracellular matrix production and muscle formation.

Background Despite the proven efficacy of liposuction, there is a population of patients who prefer non-surgical alternatives. Laser hyperthermia-induced lipolysis has emerged as one non-invasive alternative to liposuction. Objectives The authors sought to evaluate the safety and efficacy of a 1060-nm (±10 nm) diode laser for non-invasive fat reduction of the abdomen. Methods This single-arm, 2-center study enrolled 30 patients. Patients received a 25-minute 1060-nm diode laser treatment on their abdomen. Ultrasound adipose measurements, body weight, and circumference were taken at baseline and at 6- and 12-week follow-up visits. Blinded evaluators identified “before” and “after” photos of each patient. A patient satisfaction questionnaire was completed by each patient at study exit. Results A total 29 patients completed all treatment and follow-up visits. Ultrasound images showed an adipose reduction of 8.55% at 12 weeks post-treatment (P Conclusions These results indicate that a single treatment with a 1060-nm (±10 nm) diode laser, per the treatment protocol, is safe and effective in reducing unwanted fat in the abdomen as objectively measured employing ultrasound. The treatment was well-tolerated among all patients, with minimal discomfort reported and high patient satisfaction. Level of Evidence: 4

Object In previous studies of traumatic brain injury (TBI), neural biomarkers of injury correlate with injury severity and predict neurological outcome. The object of this paper was to characterize neurofilament-H (NFL-H) as a predictor of injury severity in patients who have suffered mild TBI (mTBI). Thus, the authors hypothesized that phosphorylated NFL-H (pNFL-H) levels are higher in mTBI patients than in healthy controls and identify which subjects experienced a more severe injury such as skull fractures, intracranial hemorrhaging, and/or contusions as detected by CT scans. Methods In this prospective clinical study, blood (8 ml) was collected from subjects (n = 34) suffering from mTBI (as defined by the American Congress of Rehabilitation and Glasgow Coma Scale scores between 13 and 15) at Parkland Hospital, Dallas, Texas, on Days 1 and 3 after injury). Additional clinical findings from the CT scans were also used to categorize the TBI patients into those with and those without clinical findings on the scans (CT+ and CTgroups, respectively). The serum levels of pNFL-H were measured using the enzyme-linked immunosorbent assay. Results Compared with healthy controls, the mTBI patients exhibited a significant increase in the serum levels of pNFL-H on Days 1 (p = 0.00001) and 3 (p = 0.0001) after TBI. An inverse correlation was observed between pNFL-H serum levels and Glasgow Coma Scale scores, which was significant. Additionally, using receiver operating characteristic curve analysis to compare the mTBI cases with controls to determine sensitivity and specificity, an area under the curve of 100% was achieved for both (p = 0.0001 for both). pNFL-H serum levels were only significantly higher on Day 1 in mTBI patients in the CT+ group (p < 0.008) compared with the CT− group. The area under the curve (82.5%) for the CT+ group versus the CT− group was significant (p = 0.021) with a sensitivity of 87.5% and a specificity of 70%, using a cutoff of 1071 pg/ml of pNFL-H in serum. Conclusions This study describes the serum profile of pNFL-H in patients suffering from mTBI with and without CT findings on Days 1 and 3 after injury. These results suggest that detection of pNFL-H may be useful in determining which individuals require CT imaging to assess the severity of their injury.

Clinical studies conducted in intensive care units are associated with logistical and ethical challenges. Diseases investigated are precipitous and life-threatening, care is highly technological, and patients are often incapacitated and decision-making is provided by surrogates. These investigations increasingly involve collection of genetic data. The manner in which the exigencies of critical illness impact attitudes regarding genetic data collection is unstudied. Given interest in understanding stakeholder preferences as a foundation for the ethical conduct of research, filling this knowledge gap is timely. The conduct of opinion research in the critical care arena is novel. This brief report describes the development of parallel patient/surrogate decision-maker quantitative survey instruments for use in this environment. Future research employing this instrument or a variant of it with diverse populations promises to inform research practices in critical illness gene variation research.
