Auricular acupressure for overweight and obese individuals: A systematic review and meta-analysis.

BACKGROUND: Auricular acupressure has been used for treating obesity, but inconsistent outcomes have been reported. Moreover, systematic reviews and meta-analyses have seldom addressed the effects of auricular acupressure and duration of treatment in overweight/obese individuals. This study reviewed research articles on auricular acupressure for weight reduction, analyzed the related effects on obesity, and explored the relationships between weight reduction and treatment duration, as well as outcome variables. METHODS: We searched PubMed, Cochrane Library, CINAHL, MEDLINE with Full Text, National Digital Library of Theses and Dissertation in Taiwan, and Airiti Library for articles up to July 4, 2018. Eight eligible trials were identified for qualitative synthesis, and one of them was excluded from quantitative synthesis. Inclusion criteria were as follows: intervention contained auricular acupressure, study subjects were overweight and/or obese, as defined by published authors, and the study design had 2 or more arms for comparison. RESULTS: Pooled analysis of the 7 remaining studies revealed that auricular acupressure alone, or with diet and/or exercise, was effective for weight reduction, particularly for decreasing body weight (BW), body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), body fat mass (BFM), and body fat percentage (BFP), compared with no treatment, sham treatment, or use of surgical tape with diet and/or exercise. However, there was no effect on hip circumference. A 12-week acupressure intervention was associated with a larger effect on lowering BW and BMI compared with 4-, 6-, and 8-week interventions. The methodologic quality of trials included in the quantitative synthesis ranged from scores 2 to 6 based on the modified Jadad scale. Additionally, this meta-analysis combined studies that used different acupoints and outcomes evaluated at different timepoints, which may have been potential sources of bias. CONCLUSION: The study results indicate that auricular acupressure is effective for weight reduction. However, further vigorous studies that use double-blind randomized controlled design are needed to verify these findings. WC, WHR, BFP, or BFM should be used as obesity-related parameters in weight reduction studies to detect changes in fat, muscle, and skeletal weight.

Neonatal vaccination with plasmid DNA encoding Cyn d 1 effectively prevents allergic responses in mice.

BACKGROUND: Allergic rhinitis is one of the most common atopic disorders in children. There is no available method to prevent airway sensitization in newborns except allergen avoidance. Recombinant DNA plasmids encoding allergens have been proven to activate Th1 but attenuate Th2-deviated allergic responses in adult animal studies. However, their preventive effects are not presumptive in neonates because of their immature immune function. The aim of this study was to examine the potential preventive effect of a DNA vaccine encoding grass pollen allergen Cyn d 1 on allergic reaction to grass pollen in neonatal mice. METHODS: Recombinant plasmid Cyn d 1 (pCyn d 1) vaccine was constructed by insertion of Cyn d 1 cDNA into the vector pcDNA3. Neonatal BALB/c mice received the vaccine once on the 3rd day of life or a second dose 2 days later. Control mice received PBS only. Mice were sensitized twice with recombinant Cyn d 1 and alum beginning at 7 weeks of age. Serum antibody responses and cytokine profiles of spleen cells were examined. RESULTS: Neonatal injection with pCyn d 1 vaccine resulted in IgG2a responses and production of interferon gamma in spleen cells. Vaccination with pCyn d 1 also reduced specific IgE responses and spleen cell secretion of IL-4. CONCLUSION: This study shows the prophylactic effects of DNA vaccine encoding Bermuda grass pollen allergen Cyn d 1 on specific IgE responses in neonatal mice.

Antimicrobial susceptibility of Staphylococcus aureus in children with atopic dermatitis.

BACKGROUND: Skin infection and/or nasal carriage of Staphylococcus aureus in children with atopic dermatitis (AD) is a risk factor for exacerbating disease or subsequent recurrent S. aureus infection. The purpose of the study is to evaluate the antibiotic susceptibilities of S. aureus strains from AD children and determine the most appropriate choice of antibiotics. METHODS: Nasal swabs from 168 healthy children with AD and 20 AD children with concurrent skin and soft-tissue infections (SSTI) were collected in 2005-2008. S. aureus strains were further analyzed for and compared with antibiotic susceptibilities. RESULTS: There were 78 (46.4%) healthy children with AD colonized with S. aureus, and 24 (30.8%) were methicillin-resistant S. aureus (MRSA). Among the 20 SSTI-infecting strains, 12 (60%) were MRSA. Antimicrobial susceptibility testing showed that, after penicillin, colonizing and SSTI-infecting strains had the highest rates of resistance to erythromycin (50% and 70%, respectively). All isolated strains were susceptible to vancomycin, rifampin, and mupirocin. Multi-drug resistance was found in 70% of the colonizing and 50% of the SSTI-infecting strains. D-test assay revealed inducible clindamycin resistance in 75% of the colonizing strains. The most prevalent resistance gene was ermB which was present in 94.9% and 92.9% of colonizing and SSTI-infecting strains, respectively. CONCLUSIONS: This study found that colonizing and SSTI-infecting strains of S. aureus from AD children had a high prevalence of MRSA and multi-drug resistance. Trimethoprim-sulfamethoxazole, rifampin, fusidic acid and mupirocin appear to be more suitable for treatment and decolonization of S. aureus in AD children.
