Aims This study examines the preliminary outcomes of an intervention targeting service providers in methadone maintenance therapy ( MMT) clinics in China. The intervention effects on both service providers and clients are reported. Design The MMT CARE intervention pilot was developed and implemented collaboratively with local health educators. After three group intervention sessions, trained providers in intervention clinics delivered two individual motivational interviewing sessions with their clients. Settings Six clinics in Sichuan, China, were randomized to either the MMT CARE intervention condition or a standard care condition. Participants A total of 41 providers and 179 clients were sampled from the six clinics. Measurements At baseline and three-, six-, and nine-month assessments, providers completed self-administrated paper/pencil questionnaires regarding provider-client interaction, MMT knowledge, perceived job-related stigma and clinic support. Clients completed a face-to-face survey about their concurrent drug use and drug avoidance self-efficacy. Mixed-effects regression models with clinic-level random effect were used to assess the intervention effects. Findings Significant intervention effects for providers were found in improved MMT knowledge, provider-client interaction and perceived clinic support. For clients, better improvements in drug avoidance self-efficacy and reduced concurrent drug use were observed for the intervention compared with the standard care group. Conclusions The MMT CARE intervention targeting providers in methadone maintenance clinics can improve providers' treatment knowledge and their interaction with clients. The intervention can also reduce clients' drug-using behavior through motivational interviewing sessions conducted by trained providers. [ABSTRACT FROM AUTHOR]

Background and Objective Systemic macrolide antibiotic administration has been shown to result in the elimination or reduction cyclosporine A-induced gingival overgrowth. Roxithromycin ( ROX) is known to have anti-inflammatory, immunomodulatory and tissue reparative effects. This study was to evaluate the effect of adjunctive ROX therapy on cyclosporine A-induced gingival overgrowth and interleukin ( IL)-1β, transforming growth factor ( TGF)-β1 and vascular endothelial growth factor ( VEGF) levels in gingival crevicular fluid of renal transplant patients. Material and Methods Thirty-one patients with clinically significant overgrowth and 16 periodontally healthy subjects were included in this randomized, double-blind, placebo-controlled, parallel-arm study. Patients received scaling and root planing ( SRP) at baseline and randomized to take either ROX or placebo for 5 d. The clinical parameters, including plaque index, papillary bleeding index, probing depth and gingival overgrowth scores, were recorded. The amounts of IL-1β, TGF-β1 and VEGF in gingival crevicular fluid were detected by ELISA. Periodontal parameters as well as gingival crevicular fluid biomarker levels were evaluated at baseline and at 1 and 4 wk post-therapy. Results Following SRP plus ROX and SRP plus placebo therapy, significant improvements in clinical periodontal parameters of both study groups were observed ( p < 0.025). In the ROX group, adjunctive ROX therapy resulted in a greater gingival overgrowth scores reduction compared with those in the placebo group at 4 wk ( p < 0.017). Initial amounts of IL-1β, TGF-β1 and VEGF for both the ROX and placebo groups were significantly higher than those for healthy subjects ( p < 0.017), with no statistical difference between the two study groups. At 1 and 4 wk post-therapy, significant decreases in the amounts of IL-1β, TGF-β1 and VEGF were observed in both study groups when compared with baseline ( p < 0.025), but there was no difference in the levels of IL-1β and VEGF between the two study groups. The amount of decrease in TGF-β1 levels for the ROX group was statistically significant compared to that for the placebo group at 4 wk after treatment ( p < 0.017). Conclusion Our study indicated that combination of ROX with non-surgical therapy improves gingival overgrowth status and decreases gingival crevicular fluid TGF-β1 levels in patients with severe gingival overgrowth. The reduction of gingival crevicular fluid TGF-β1 following ROX therapy suggests an anti-inflammatory/immunomodulatory effect of ROX on the treatment of cyclosporine A-induced gingival overgrowth.

Aim To investigate the effects of two natural compounds-containing mouthrinses ( NCCMs) (a fructus mume ( FM) extract-containing mouthrinse and an essential oil ( EO)-containing mouthrinse) on gingival health and microbial profiles in young orthodontic patients. Design This 6-month randomized, single-blinded, parallel-controlled clinical trial consists of 90 patients with fixed appliance treatment. The subjects were allocated to (1) negative control group: oral hygiene instruction ( OHI) alone; (2) test group 1: OHI plus EO mouthrinse; and (3) test group 2: OHI plus FM mouthrinse. Clinical examinations included plaque index ( PI), bleeding index ( BI) and modified gingival index ( MGI). Salivary microbial quantifications included total aerobic and anaerobic bacteria, Streptococci and Lactobacilli counts. Clinical and microbiological examinations were conducted at baseline, 3rd and 6th months ( T1, T2, and T3). Results BI was significantly reduced in both the FM mouthrinse and EO mouthrinse groups compared with the negative control group at T3 ( P < 0.05). There were no significant intergroup differences in salivary bacteria counts in all groups ( P > 0.05). Conclusion Both NCCMs effectively reduced gingival bleeding without causing significant alterations of microbial profile in young orthodontic patients. [ABSTRACT FROM AUTHOR]

Inappropriate complementary feeding practices have led to, in part, significant disparities in growth and nutritional status between rural and urban children in China. A cluster-randomised, controlled trial was implemented in Laishui, China to assess the effectiveness of an educational intervention on caregivers' feeding practices and children's growth. Eight townships were randomly assigned to the intervention or control. Five hundred ninety-nine healthy infants were enrolled at 2-4 months old, and were followed up at ages 6, 9, 12, 15 and 18 months. The intervention group received information on enhanced home-prepared recipes and food preparation and hygiene through group training, counselling and home visit. Key outcomes were children's physical growth, caregivers' knowledge and behaviours on complementary feeding, and the infant and child feeding index ( ICFI). Analysis was by intention to treat. The intervention group achieved better knowledge and practices related to complementary feeding, and significantly higher ICFI scores at each follow-up point. Children in the intervention group achieved higher z-scores for weight-for-age ( WAZ) and weight-for-height ( WHZ) than the control (0.18 vs. 0.01 and 0.49 vs. 0.19, respectively) at 18 months old, and were less likely to have stunted growth (odds ratio = 0.71, 95% confidence interval: 0.53-0.94). Mixed model showed that the intervention group achieved significantly better linear growth over time, including WAZ ( P = 0.016), WHZ ( P = 0.030) and HAZ ( P = 0.078). These results indicated that an educational intervention delivered through local health services can enhance caregivers' knowledge and practices of complementary feeding and ultimately improve children's growth.
