Factors Associated With Weight Loss After Laparoscopic Adjustable Gastric Banding in Adolescents With Severe Obesity.

Unlabelled: Childhood obesity is associated with many comorbidities. Bariatric surgery is known to be efficient for reducing weight in adolescents.

Objectives: The primary outcome was to identify somatic or psychosocial factors associated with success at 24 months after a laparoscopic adjustable gastric banding (LAGB) procedure in our cohort of adolescents with severe obesity.

High-performance thin-layer chromatography with atmospheric solids analysis probe mass spectrometry for analysis of gasoline polymeric additives.

Rationale: The offline coupling of high-performance thin-layer chromatography (HPTLC) with atmospheric solids analysis probe mass spectrometry (ASAP-MS) was evaluated for the characterization of polymeric additives in gasoline.

Methods: A protocol was developed to optimize the ion signal. A glass capillary was moistened with deionized water, and then dipped into silica gel scratched from an HPTLC plate.

Characterization of polyalphaolefins using halogen anion attachment in atmospheric pressure photoionization coupled with ion mobility spectrometry-mass spectrometry.

Polyalphaolefins (PAOs) are saturated alpha olefin oligomers used as a base stock oil for synthetic lubricants. The synthetic base stocks are manufactured from linear alpha olefins by catalytic oligomerization processes. The aim of this work was the characterization of different PAO grades, synthesized from different linear alpha olefins using two oligomerization processes, acid and metallocene catalyses.

Atmospheric Solid Analysis Probe Coupled to Ion Mobility Spectrometry-Mass Spectrometry, a Fast and Simple Method for Polyalphaolefin Characterization.

Polyalphaolefins (PAOs) are polymers produced from linear alpha olefins through catalytic oligomerization processes. The PAOs are known as synthetic high-performance base stock fluids used to improve the efficiency of many other synthetic products. In this study, we report the direct characterization of PAOs using atmospheric solid analysis probe (ASAP) coupled with ion mobility spectrometry-mass spectrometry (IMS-MS).

Laparoscopic adjustable gastric banding in adolescents with severe obesity: Psychological aspects, decision makers of surgery, and 2-year outcomes. A case series.

Background: The results of medical treatment of severe obesity in the adolescent population (balanced diet and physical activity) are often unsatisfactory, and bariatric surgery is questioned. The psychological determinants for requesting bariatric surgery in these adolescents are unclear. The objective of this study was to report the psychiatric and psychological aspects as well as the determinants of the medical decision for surgery in a cohort of obese adolescents requesting bariatric surgery by laparoscopic adjustable gastric banding.

Bariatric surgery in adolescents with severe obesity: Review and state of the art in France.

Severe obesity (body mass index>120% of BMI IOTF-30 cut off) and morbid obesity (BMI>140% of BMI IOTF-30 cut off) affect 5 to 10% of obese adolescents in France. Organic complications can be found in about 50% of these patients, and depressive symptoms in one-third of them. Finally, over 70% will suffer from adult morbid obesity associated with a marked increase in morbidity and mortality.

Laparoscopic adjustable gastric banding in adolescents: Results at two years including psychosocial aspects.

Background/purpose: Obesity now affects 3%-4% of the pediatric population and contributes to the increase in cardiac mortality in adulthood. Bariatric surgery is the best treatment for weight loss and the obesity-associated comorbidities in adults. We report here our experience of laparoscopic adjustable gastric banding (LAGB) in adolescents.

Optimization of the isolation and quantitation of kahweol and cafestol in green coffee oil.

Kahweol and cafestol are two diterpenes that exist mainly as esters of fatty acids in green coffee oil. To recover them under their free form they have to be either saponified or trans-esterified. These two compounds are well known to be sensitive to heat, and reagents, therefore experimental conditions used in the transesterification reaction are critical.

[Adolescent with anorexia nervosa: consequences on bone mineralization].

Introduction: Anorexia nervosa is responsible for abnormalities in bone mineralization, which are well known and described in adults, but less well documented in adolescents. The aim of this research was to evaluate the frequency and severity and to determine predictive factors for these abnormalities in a population of adolescents with diagnosed anorexia nervosa.

Patients And Methods: This retrospective study involved 39 female adolescents with anorexia nervosa having undergone dual energy X-ray absorptiometry prior to the age of 18 years.

[Body composition analysis in patients with cystic fibrosis. Comparison of 3 methods: dual energy x-ray absorptiometry, bioelectrical impedance analysis, and skinfold measurements].

Nutritional status must be closely monitored in cystic fibrosis (CF) patients. This study compared three methods of measuring body composition in CF patients and then examined the relationships between two simple anthropometric markers of nutritional status - tricipital skinfold thickness (TSK) and arm muscular circumference (AMC) - and the results given by each method. Fifty-five patients with CF, 27 females and 28 males, participated in this study.
