    Abstract Background: Metabolic and bariatric surgery (MBS) is safe and efficacious in treating adolescents with severe obesity. Behavioral/lifestyle programs can support successful preparation for surgery and post-MBS weight loss, but no standardized lifestyle intervention exists for adolescents. Here we describe the process of developing and adapting the Diabetes Prevention Program Group Lifestyle Balance (DPP/GLB) curriculum to support adolescents pre- and post-MBS.
    Methods: We collected both qualitative and quantitative data from a diverse group of adolescents (N = 19, mean age 15.2 years, range 13-17, 76% female, 42% non-Hispanic Black, 41% Hispanic, 17% other). Additionally, we included data from 13 parents, all of whom were mothers. These participants were recruited from an adolescent MBS program at Children's Health System of Texas. In an online survey, we asked participants to rank their preferences and interests in DPP/GLB content topics. We complemented these results with in-depth interviews from a subset of 10 participants. This qualitative data triangulation informed the development of the TeenLYFT lifestyle intervention program, designed to support adolescents who were completing MBS and described here. This program was adapted from adolescent and parent DPP/GLB content preferences, incorporating the social cognitive model (SCM) and the socioecological model (SEM) constructs to better cater to the needs of adolescent MBS patients.
    Results: Adolescents' top 3 ranked areas of content were: (1) steps to adopt better eating habits and healthier foods; (2) healthy ways to cope with stress; and (3) steps to stay motivated and manage self-defeating thoughts. Nearly all adolescent participants preferred online delivery of content (versus in-person). Mothers chose similar topics with the addition of information on eating healthy outside the home. Key themes from the adolescent qualitative interviews included familial support, body image and self-confidence, and comorbidities as key motivating factors in moving forward with MBS.
    Conclusions: The feedback provided by both adolescents and parents informed the development of TeenLYFT, an online support intervention for adolescent MBS candidates. The adapted program may reinforce healthy behaviors and by involving parents, help create a supportive environment, increasing the likelihood of sustained behavior change. Understanding adolescent/parent needs to support weight management may also help healthcare providers improve long-term health outcomes for this patient population.

    Abstract The most-severe form of congenital generalized lipodystrophy (CGL) is caused by mutations in BSCL2/seipin. Seipin is a homo-oligomeric integral membrane protein in the endoplasmic reticulum that concentrates at junctions with cytoplasmic lipid droplets (LDs). While null mutations in seipin are responsible for lipodystrophy, dominant mutations cause peripheral neuropathy and other nervous system pathologies. We first review the clinical aspects of CGL and the discovery of the responsible genetic loci. The structure of seipin, its normal isoforms, and mutations found in patients are then presented. While the function of seipin is not clear, seipin gene manipulation in yeast, flies, mice, and human cells has recently yielded a trove of information that suggests roles in lipid metabolism and LD assembly and maintenance. A model is presented that attempts to bridge these new data to understand the role of this fascinating protein.

    Abstract Seipin is necessary for both adipogenesis and lipid droplet (LD) organization in nonadipose tissues; however, its molecular function is incompletely understood. Phenotypes in the seipin-null mutant of Saccharomyces cerevisiae include aberrant droplet morphology (endoplasmic reticulum-droplet clusters and size heterogeneity) and sensitivity of droplet size to changes in phospholipid synthesis. It has not been clear, however, whether seipin acts in initiation of droplet synthesis or at a later step. Here we utilize a system of de novo droplet formation to show that the absence of seipin results in a delay in droplet appearance with concomitant accumulation of neutral lipid in membranes. We also demonstrate that seipin is required for vectorial budding of droplets toward the cytoplasm. Furthermore, we find that the normal rate of droplet initiation depends on 14 amino acids at the amino terminus of seipin, deletion of which results in fewer, larger droplets that are consistent with a delay in initiation but are otherwise normal in morphology. Importantly, other functions of seipin, namely vectorial budding and resistance to inositol, are retained in this mutant. We conclude that seipin has dissectible roles in both promoting early LD initiation and in regulating LD morphology, supporting its importance in LD biogenesis.

    Abstract In Saccharomyces cerevisiae, the sequence-specific binding of the negative regulator Rap1p provides a mechanism to measure telomere length: as the telomere length increases, the binding of additional Rap1p inhibits telomerase activity in cis. We provide evidence that the association of Rap1p with telomeric DNA in vivo occurs in part by sequence-independent mechanisms. Specific mutations in EST2 (est2-LT) reduce the association of Rap1p with telomeric DNA in vivo. As a result, telomeres are abnormally long yet bind an amount of Rap1p equivalent to that observed at wild-type telomeres. This behavior contrasts with that of a second mutation in EST2 (est2-up34) that increases bound Rap1p as expected for a strain with long telomeres. Telomere sequences are subtly altered in est2-LT strains, but similar changes in est2-up34 telomeres suggest that sequence abnormalities are a consequence, not a cause, of overelongation. Indeed, est2-LT telomeres bind Rap1p indistinguishably from the wild type in vitro. Taken together, these results suggest that Est2p can directly or indirectly influence the binding of Rap1p to telomeric DNA, implicating telomerase in roles both upstream and downstream of Rap1p in telomere length homeostasis.

    Abstract Objective: To determine the incidence of carpal tunnel syndrome (CTS) over 1 year in Latino poultry processing workers.
    Methods: Symptoms and nerve conduction studies were used to identify Latino poultry processing workers (106 wrists) and Latinos in other manual labor occupations (257 wrists) that did not have CTS at baseline, and these individuals were then evaluated in the same manner 1 year later.
    Results: Based on wrists, the 1-year incidence of CTS was higher in poultry processing workers than non-poultry manual workers (19.8% vs. 11.7%, P = 0.022). Poultry workers had a higher odds (1.89; P = 0.089) of developing CTS over 1 year compared to non-poultry manual workers.
    Discussion: Latino poultry processing workers have an incidence of CTS that is possibly higher than Latinos in other manual labor positions. Latino poultry workers' high absolute and relative risk of CTS likely results from the repetitive and strenuous nature of poultry processing work.
