        Effectiveness of obesity interventions among South Korean children and adolescents and importance of the type of intervention component: a meta-analysis

        Choe Siyoung,Sa Jaesin,Chaput Jean-Philippe,Kim Deokjin 대한소아청소년과학회 2022 Clinical and Experimental Pediatrics (CEP) Vol.65 No.2

        Background: Various interventions have been tested to prevent or treat childhood obesity in South Korea. However, the overall effect of those interventions is unclear, as very few reviews and meta-analyses were specific to Korean children and adolescents.Purpose: We aimed to examine the overall effect of obesity interventions among Korean children and adolescents, while also examining differences by sex, age group, baseline weight category, intervention duration, number of intervention components, and type of intervention components.Methods: A meta-analysis was conducted for all intervention studies sampling Korean children and adolescents, with at least one control group and one month of follow-up, published between January 2000 and August 2020. Cohen d was calculated as an effect size for treatment effect, using the standardized difference between intervention group’s body mass index (BMI) change and control group’s BMI change.Results: The final sample included 19 intervention studies with 2,140 Korean children (mean age, 12.2 years). Overall, interventions were strongly favored over their controls (d=1.61; 95% confidence interval [CI], 1.12–2.09). The subgroup analysis showed that interventions with at least one physical activity component (d=2.43; 95% CI, 1.63–3.24) were significantly better than those that did not include physical activity (d=0.02; 95% CI, -0.26 to 0.31).Conclusion: Type of intervention component appeared important, though no differential association was observed by sex, age, baseline weight category, intervention duration, and number of intervention components. Korean and non-Korean interventions may be substantively different. Additional studies are needed to understand why and how Korean interventions differ from non-Korean interventions.

        Sex differences in weight perception and weight gain among Black college students in the USA

        Jounghee Lee,Sa Jaesin,Jean-Philippe Chaput,James Heimdal,Beatrice Nelson,Beom-Young Cho,Elizabeth Kwon 질병관리본부 2021 Osong Public Health and Research Persptectives Vol.12 No.2

        Objectives: The aims of this study were to examine the prevalence of overweight/obesity and to explore sex differences in body weight perceptions and correlates of weight gain among Black students at 2 historically Black colleges and universities (HBCUs) in the USA. Methods: Participants completed a paper-based survey, and their height and weight were measured (67% completion rate). Results: The overweight and obesity rates were 33.8% and 26.9%, respectively. More females than males accurately assessed their weight (p<0.05). Body weight underestimation was associated with male sex, excellent/very good perceived overall health, and not being informed by a doctor of having overweight or obesity (p<0.01). Higher odds of ≥5% weight gain were related to female sex, living on campus, and not being informed by a doctor of having overweight or obesity (p<0.05). Conclusion: Given the high overweight and obesity rates among Black students, HBCUs in the USA should develop intervention strategies for the prevention and management of overweight and obesity. College health educators at HBCUs need to provide regular check-ups or health screenings that help male students perceive their weight accurately and prevent weight underestimation. It is important for HBCUs to monitor and address weight gain among Black students as early as possible.

        Prevalence and correlates of highly caffeinated beverage consumption among Korean adolescents

        곽호경,Jaesin Sa,Siyoung Choe,Jean-Philippe Chaput,Joon Chung,Gayle Cummings,이정희 질병관리본부 2021 Osong Public Health and Research Persptectives Vol.12 No.6

        Objectives: The purposes of this study were to (1) examine the multi-year prevalence of highly caffeinated beverage (HCB) consumption, (2) identify sex differences in the prevalence, and (3) investigate relationships between HCB consumption and behavioral characteristics in a nationally representative sample of Korean adolescents.Methods: Data from the Korea Youth Risk Behavior Web-based Survey (2014–2017) were analyzed.Results: HCB consumption was higher in 2017 than 2014 (23.9% vs. 12.0%), and higher among boys than girls (17.2% vs. 13.1%). HCB drinkers were more likely to (1) be boys, (2) be overweight or obese, (3) use alcohol and tobacco, (4) consume soda at least once per week, (5) consume sweetened beverages at least once per week, (6) have seriously considered suicide during the past 12 months, and (7) have attempted suicide during the past 12 months (p<0.05 for all).Conclusion: Effective programs to curb HCB consumption among Korean adolescents need to be established.

      • Peptidoglycan molecular requirements allowing detection by the Drosophila immune deficiency pathway.

        Stenbak, Carolyn R,Ryu, Ji-Hwan,Leulier, Franç,ois,Pili-Floury, Sebastien,Parquet, Claudine,Hervé,, Mireille,Chaput, Catherine,Boneca, Ivo G,Lee, Won-Jae,Lemaitre, Bruno,Mengin-Lecreulx, D Williams Wilkins 2004 JOURNAL OF IMMUNOLOGY Vol.173 No.12

        <P>Innate immune recognition of microbes is a complex process that can be influenced by both the host and the microbe. Drosophila uses two distinct immune signaling pathways, the Toll and immune deficiency (Imd) pathways, to respond to different classes of microbes. The Toll pathway is predominantly activated by Gram-positive bacteria and fungi, while the Imd pathway is primarily activated by Gram-negative bacteria. Recent work has suggested that this differential activation is achieved through peptidoglycan recognition protein (PGRP)-mediated recognition of specific forms of peptidoglycan (PG). In this study, we have further analyzed the specific PG molecular requirements for Imd activation through the pattern recognition receptor PGRP-LC in both cultured cell line and in flies. We found that two signatures of Gram-negative PG, the presence of diaminopimelic acid in the peptide bridge and a 1,6-anhydro form of N-acetylmuramic acid in the glycan chain, allow discrimination between Gram-negative and Gram-positive bacteria. Our results also point to a role for PG oligomerization in Imd activation, and we demonstrate that elements of both the sugar backbone and the peptide bridge of PG are required for optimum recognition. Altogether, these results indicate multiple requirements for efficient PG-mediated activation of the Imd pathway and demonstrate that PG is a complex immune elicitor.</P>

        New techniques for wound management: A systematic review of their role in the management of chronic wounds

        Farid Bekara,Julian Vitse,Sergiu Fluieraru,Raphael Masson,Antoine De Runz,Vera Georgescu,Guillaume Bressy,Jean Louis Labbé,Benoit Chaput,Christian Herlin 대한성형외과학회 2018 Archives of Plastic Surgery Vol.45 No.2

        Debridement is a crucial component of wound management. Recent technologies such as hydrosurgery (Versajet), ultrasound therapy (the MIST therapy device), or plasma-mediated bipolar radio-frequency ablation therapy (Coblation) seem to represent interesting alternatives for wound debridement. The purpose of this systematic review was to describe, evaluate, and compare these three recently developed methods for the management of chronic wounds. In January 2016, an electronic database search was conducted of MEDLINE, PubMed Central, and Embase for articles concerning these three innovative methods for the management of chronic wounds. A total of 389 references were identified by our search strategy, and 15 articles were included. We extracted data regarding the number and age of patients, indications, operating time, number of procedures, costs, wound healing time, decrease in exudation, perioperative blood loss, bacterial load, and the occurrence of complications. The 15 articles included studies that involved 563 patients who underwent hydrosurgery (7 studies), ultrasound therapy (6 studies), or Coblation (2 studies). Six randomized controlled trials were included that compared the use of a scalpel or curette to hydrosurgery (2 studies) or ultrasound therapy (6 studies). Hydrosurgery, in addition to being a very precise and selective tool, allows significantly faster debridement. Ultrasound therapy provides a significant reduction of exudation, and improves the wound healing time. No comparative study dedicated to Coblation was identified. Despite the obvious clinical interest of the topic, our review of the current literature revealed a lack of prospective randomized studies comparing these devices with each other or with standard techniques, particularly for Coblation and hydrosurgery.
