Abstract
BACKGROUND In 2016, the Patient-Centered Outcomes Research Institute funded the National Patient Centered Clinical Research Network (PCORnet) Bariatric Study (PBS). Understanding the experience of postoperative patients was a key component of this study. METHODS Nine focus groups were conducted in Southern California, Louisiana, Pennsylvania, and Ohio and in a national advocacy conference for patients with obesity. Participants were identified and recruited in both clinical and community settings. Focus group transcripts were analyzed using an iterative inductive-deductive approach to identify global overarching themes. RESULTS There were 76 focus group participants. Participants were mostly women (81.4%), had primarily undergone gastric sleeve (47.0%), were non-Hispanic white (51.4%), had some college education (44.3%), and made $100,000 annual income or less (65.7%). Qualitative findings included negative reactions patients received from friends, family, and co-workers once they disclosed that they had bariatric surgery to lose weight; and barriers to follow-up care included insurance coverage, emotional and situational challenges, and physical pain limiting mobility. CONCLUSIONS These findings confirm the other qualitative findings in this area. The approach to bariatric surgery should be expanded to provide long-term comprehensive care that includes in-depth postoperative lifetime monitoring of emotional and physical health.

Abstract
BACKGROUND There has been a dramatic shift in use of bariatric procedures, but little is known about their long-term comparative effectiveness. OBJECTIVE To compare weight loss and safety among bariatric procedures. DESIGN Retrospective observational cohort study, January 2005 to September 2015. (ClinicalTrials.gov: NCT02741674). SETTING 41 health systems in the National Patient-Centered Clinical Research Network. PARTICIPANTS 65 093 patients aged 20 to 79 years with body mass index (BMI) of 35 kg/m2 or greater who had bariatric procedures. INTERVENTION 32 208 Roux-en-Y gastric bypass (RYGB), 29 693 sleeve gastrectomy (SG), and 3192 adjustable gastric banding (AGB) procedures. MEASUREMENTS Estimated percent total weight loss (TWL) at 1, 3, and 5 years; 30-day rates of major adverse events. RESULTS Total numbers of eligible patients with weight measures at 1, 3, and 5 years were 44 978 (84%), 20 783 (68%), and 7159 (69%), respectively. Thirty-day rates of major adverse events were 5.0% for RYGB, 2.6% for SG, and 2.9% for AGB. One-year mean TWLs were 31.2% (95% CI, 31.1% to 31.3%) for RYGB, 25.2% (CI, 25.1% to 25.4%) for SG, and 13.7% (CI, 13.3% to 14.0%) for AGB. At 1 year, RYGB patients lost 5.9 (CI, 5.8 to 6.1) percentage points more weight than SG patients and 17.7 (CI, 17.3 to 18.1) percentage points more than AGB patients, and SG patients lost 12.0 (CI, 11.6 to 12.5) percentage points more than AGB patients. Five-year mean TWLs were 25.5% (CI, 25.1% to 25.9%) for RYGB, 18.8% (CI, 18.0% to 19.6%) for SG, and 11.7% (CI, 10.2% to 13.1%) for AGB. Patients with diabetes, those with BMI less than 50 kg/m2, those aged 65 years or older, African American patients, and Hispanic patients lost less weight than patients without those characteristics. LIMITATION Potential unobserved confounding due to nonrandomized design; electronic health record databases had missing outcome data. CONCLUSION Adults lost more weight with RYGB than with SG or AGB at 1, 3, and 5 years; however, RYGB had the highest 30-day rate of major adverse events. Small subgroup differences in weight loss outcomes were observed. PRIMARY FUNDING SOURCE Patient-Centered Outcomes Research Institute.

Abstract
In the present paper a novel mechanochemical process for the elimination of organic pollutants dissolved in water is proposed. In this regard, phenol aqueous solutions (100mgL(-1)) were ball-milled for 0, 12, 18, 24, 36, 48, and 72h with and without a well-characterized (XRD, SEM, and N(2) Adsorption), rutile powder catalyst and the reaction products analyzed with UV and GC/MS. It was found that when the catalyst was not included in the process, phenol was not affected, but when it was included, phenol was decomposed. The catalyst itself did not change and the reaction follows a pseudo-first-order kinetics. Besides, intermediates which are characteristic of the ()OH radical mechanism were found in the reaction products. Then, a mechanism similar to those accepted for other advanced oxidation processes was proposed. The value measured for the pseudo-first-order reaction constant was very low, indicating that the reported process is inefficient. Nevertheless, this problem could be solved by applying catalysts consisting of particles with smaller diameters.

Abstract
The delta 5,9 fatty acids (5Z,9Z)-5,9-hexadecadienoic acid, (5Z,9Z)-5,9-nonadecadienoic acid, and (5Z,9Z)-5,9-eicosadienoic acid were synthesized for the first time in four steps (9-12% overall yield) starting from commercially available 2-(2-bromoethyl)-1,3-dioxolane. The synthetic approach provided enough material to corroborate the structure and stereochemistry of (5Z,9Z)-5,9-nonadecadienoic acid which was recently identified in the flowers of Malvaviscus arboreus (Malvaceae). The novel phospholipids 1-hexadecanoyl-2-[(5Z,9Z)-5,9-eicosadienoyl]-sn-glycer o-3-phosphocholine and 1-octadecanoyl-2-[(5Z,9Z)-5,9-eicosadienoyl]-sn- glycero-3-phosphocholine were also synthesized from commercially available L-alpha-phosphatidylcholine (egg yolk) and characterized by positive ion electrospray mass spectrometry. These are the first examples of unsymmetrical phospholipids with saturated fatty acids at the sn-1 position and delta 5,9 fatty acids at the sn-2 position.

Abstract
The total synthesis of the naturally occurring (Z)-2-methoxy-5-hexadecenoic acid and (Z)-2-methoxy-6-hexadecenoic acid was accomplished using as a key step Mukaiyama's trimethylsilyl cyanide addition to 4- and 5-pentadecenal, respectively. These syntheses further confirm the structures of the natural marine fatty acids and corroborate their cis double-bond stereochemistry. The title compounds were antimicrobial against the Gram-positive bacteria Staphylococcus aureus (MIC 0.35 micromol/mL) and Streptococcus faecalis (MIC 0.35 micromol/mL).

Abstract
The fatty acid composition of a Pseudomonas sp. (Alteromonas) and its host, the dinoflagellate Ostreopsis lenticularis, vectors in ciguatera fish poisoning, has been studied. The major fatty acids in O. lenticularis were 16:0, 20:5n-3, and 22:6n-3, but 18:2n-6, 18:3n-3, and 18:n-3 were also identified. In contrast to other dinoflagellates, 1 8:5n-3 was not detected in O. lenticularis. Even-chain fatty acids such as 9-16:1, 11-18:1, and 13-20:1 predominated in the Pseudomonas sp. from O. lenticularis, but 1 6-20% of (E)-11-methyl-12-octadecenoic acid was also identified. The chirality of the latter was confirmed by total synthesis (28% overall yield) starting from oxacyclotridecan-2-one. The fatty acid compositions of two other Pseudomonas species, from the palytoxin-producing zoanthids Palythoa mamillosa and P. caribdea, were also studied and were similar to that of the Pseudomonas sp. from O. lenticularis. The possibility of using some of these fatty acids as chemotaxonomic lipids in identifying marine animals that consume toxic dinoflagellates or zoanthids is discussed.

Abstract
The distribution of C14-C22 fatty acids in the phosphatidylethanolamines isolated from the sponges Agelas sp. and Spongia tampa was investigated. Selective changes with phospholipase A2 (from Agkistrodon halys blomhoffii) followed by thin-layer chromatographic separation of the resulting lysophosphatidylethanolamines and free fatty acids and subsequent methylation with HCl/MeOH and diazomethane, respectively, revealed that the 5,9-octadecadienoic acid and the 9,12-octadecadienoic acid present showed no preference for either position sn-1 or sn-2 in these phosphatidylethanolamines. The other saturated and unsaturated fatty acids with chains between 14 and 22 carbons long were also found to be equally distributed between positions sn-1 and sn-2 in the phosphatidylethanolamines in these sponges. The results contrast with what is known about the distribution in most mammalian phospholipids, such as the phosphatidylcholines from human erythrocytes, where octadecadienoic acid typically occupies the sn-2 position.

Abstract
The very long-chain fatty acids, (5E,9Z)-6-bromo-5,9-tetracosadienoic, (5E,9Z)-6-bromo-23-methyl-5,9-tetracosadienoic, (5E,9Z)-6-bromo-5,9-pentacosadienoic and (5E,9Z)-6-bromo-24-methyl-5,9- pentacosadienoic acids, were identified in the phospholipids (mainly phosphatidylethanolamine) of the sponge Agelas sp. Structure elucidation was accomplished by means of mass spectrometry and chemical transformations, including deuteration with Wilkinson's catalyst. All of the sterols from the sponge had the delta 5,7 nucleus, with 24-methylcholesta-5,7,22-trien-3 beta-ol (ergosterol) and 24-ethyl-cholesta-5,7, 22-trien-3 beta-ol being the most abundant.

Abstract
The Caribbean sponge Smenospongia aurea revealed the presence of six novel branched alpha-hydroxy fatty acids: 2-hydroxy-17-methyloctadecanoic acid, 2-hydroxy-21-methyldocosanoic acid, 2-hydroxy-22-methyltricosanoic acid, and 2-hydroxy-22-methyltetracosanoic acid, 2-hydroxy-24-methylpentacosanoic acid, and 2-hydroxy-23-methylpentacosanoic acid. These novel alpha-hydroxy fatty acids were associated with phosphatidylethanolamine. The sponges Aplysina lacunosa and Aplysina fistularis also contained considerable amounts of alpha-hydroxy fatty acids, the very long-chain 5,9,23-tricontatrienoic acid (30:3), and phytanic acid. The sterol composition of the three sponges was also studied. It indicated that A. lacunosa and A. fistularis contained large amounts of aplysterol and verongulasterol, while S. aurea did not show any of these sterols. The results are discussed in terms of the taxonomy of the species.
