NE is a relatively common finding in children with OSA symptoms. NE resolves or markedly improves in the vast majority of these patients postoperatively.

Background Liposuction and lipoabdominoplasty procedures frequently involve the treatment of the superficial and deep fatty layers of the abdomen. Objectives The aim of the present investigation was to provide comprehensive data on the thickness of the abdominal fatty layers in relation to age, gender, and body mass index (BMI). Methods The study investigated 150 Caucasian individuals; there was an equal distribution of males and females (each n = 75) and a balanced distribution of age (n = 30 per decade: 20–29, 30–39, 40–49, 50–59, and 60–69 years) and BMI (n = 50 per group: BMI ≤24.9, 25.0–29.9, and ≥30 kg/m2). Ultrasound-based measurements of the superficial and deep abdominal fatty layers were performed. Results An increase in BMI was associated with an increase in total abdominal wall fat thickness. The measured increase was related more to the thickness of the deep fatty layer than to the thickness of the superficial fatty layer (Z = 1.80, P = 0.036). An increase in age was associated with a decrease in thickness of the superficial fatty layer (rp = –0.104, P = 0.071) but with an increase in thickness of the deep fatty layer (rp = 0.197, P = 0.001). Conclusions Age and BMI can change the thickness of both the superficial and deep fatty layers of the anterior abdominal wall, thus influencing the plan and conduct of cosmetic surgical procedures. Knowledge of the layered anatomy of the anterior abdominal wall, as well as its associated blood supply, is important for surgeons performing procedures in this area.

A dynamically regulated microenvironment, which is mediated by crosstalks between adipocytes and neighboring cells, is critical for adipose tissue homeostasis and function. However, information on key molecules and/or signaling pathways regulating the crosstalks remains limited. In this study, we identify adipocyte miR-182-5p as a crucial anti-obesity molecule that stimulates beige fat thermogenesis by promoting the crosstalk between adipocytes and macrophages. miR-182-5p is highly enriched in thermogenic adipocytes and its expression is markedly stimulated by cold exposure in mice. In contrast, miR-182-5p expression is significantly reduced in adipose tissues of obese humans and mice. Knockout of miR-185-5p decreased cold-induced beige fat thermogenesis whereas overexpression of miR-185-5p increased beiging and thermogenesis in mice. Mechanistically, miR-182-5p promotes FGF21 expression and secretion in adipocytes by suppressing Nr1d1 at 5'UTR, which in turn stimulates acetylcholine synthesis and release in macrophages. Increased acetylcholine expression activates the nicotine acetylcholine receptor in adipocytes, which stimulates PKA signaling and consequent thermogenic gene expression. Our study reveals a key role of the miR-182-5p/FGF21/acetylcholine/acetylcholine receptor axis that mediates the crosstalk between adipocytes and macrophages to promote beige fat thermogenesis. Activation of the miR-182-5p-induced signaling pathway in adipose tissue may be an effective approach to ameliorate obesity and associated metabolic diseases.

erineal defects and pressure sores are frequently encountered in practice, and their management may be challenging. Colorectal cancer is the third most common cancer in the United States, with an estimated 43,300 new cases diagnosed in 2020. 1,2 An estimated 2.5 million patients yearly are treated for pressure ulcers. 3 Management of these conditions can be associated with complication rates as high as 66 percent in some series, which further compounds the costs and implications of managing these wounds. [4][5][6][7][8][9][10] Even with optimized care, they still represent a tremendous burden to health care systems, costing upward of $9.1 billion dollars per year. 3 The goal of this article is to provide an update on the newly available evidence in the management of perineal defects and pressure sores by addressing knowledge gaps and areas of controversy that exist in the reconstruction of these defects. PERINEAL RECONSTRUCTIONMany factors are known to affect the outcomes of perineal defect reconstruction. [10][11][12][13] These factors need to be considered and optimized to achieve successful reconstruction of perineal defects (Table 1). Although the restoration of sexual function is an important part of the reconstructive process, its discussion is beyond the scope of this review.Perineal reconstruction can be complicated in patients who require neoadjuvant radiation therapy before resection. Studies have shown a significant difference in local recurrence rates with increased circumferential resection margins. Patients with 10-mm margins have a 5-year survival rate of 80 percent in comparison to a 34 percent 5-year survival rate in patients with less than 1-mm
