OBJECTIVES: 1) To determine the percentage of schoolchildren who quit smoking through the KOTAK program; 2) To identify factors associated with quitting smoking in the program.
METHODS: A clustered, randomized controlled trial was conducted in schools. Self-reported smokers meeting inclusion criteria were enrolled. Data on demographics, self-reported smoking abstinence, and nicotine addiction levels were collected at baseline, three months, and six months post-intervention. Exhaled carbon monoxide was measured at all time points, and salivary cotinine was collected at three- and six-month follow-ups.
RESULTS: Six months post-intervention, 29.8% of students in intervention schools and 14.6% in control schools reported quitting smoking. The odds of quitting were higher with the KOTAK program (aOR = 2.25, 95% CI = 1.11-4.57). Factors such as age, maternal education, and baseline nicotine addiction level were protective for smoking abstinence.
CONCLUSION: The intervention group showed a higher self-reported smoking cessation rate, indicating the potential efficacy of the KOTAK program.
METHODS: The Upper Gastrointestinal (GI) Focus Group of the Asian Pacific Association of Gastroenterology-Emerging Leaders Committee developed an international survey, which was distributed to 98 clinicians in the Asia-Pacific region, compromising an online questionnaire focusing on the management of H. pylori infection.
RESULTS: Participants responded from Japan (15, 15.3%), Hong Kong (15, 15.3%), Thailand (33, 33.7%), Vietnam (23, 23.5%), Malaysia (4, 4.1%), Singapore (3, 3.1%), and others (5, 5.1%). The most common first-line eradication regimen was clarithromycin (CAM) triple therapy, including proton pump inhibitor (PPI), amoxicillin (AMPC), and CAM (64.3%) for 14 days (70.4%). The most common second-line eradication regimen was levofloxacin (LVX) triple therapy, including PPI, AMPC, and LVX (22.4%) for 14 days (67.3%). Eradication therapy was deemed necessary for all asymptomatic adults and minors (aged ≤ 17 years) currently infected with H. pylori by 81.6% and 64.3% of respondents, respectively, with 82.7% considering upper GI endoscopy for GC screening useful in the secondary prevention of GC.
CONCLUSION: There appears to be a growing consensus among clinicians, acknowledging the necessity of eradication therapy. We anticipate that this study will establish a new benchmark in preventive medicine aimed at eradicating GC in the Asia-Pacific region.
METHODS: In three double-blind phase 3 studies, patients receiving HEC or MEC were randomized 1:1 to receive oral rolapitant 180 mg or placebo prior to chemotherapy plus 5-hydroxytryptamine type 3 receptor antagonist and dexamethasone therapy. Patients completed the FLIE questionnaire on day 6 of cycle 1. Endpoints included FLIE total score, nausea and vomiting domain scores, and the proportion of patients with no impact on daily life (total score >108 [range 18-126]). We performed a prespecified analysis of the MEC/anthracycline-cyclophosphamide (AC) study and a post hoc analysis of two pooled cisplatin-based HEC studies.
RESULTS: In the pooled HEC studies, rolapitant significantly improved the FLIE total score (114.5 vs 109.3, p control; similar results were observed in the MEC/AC study for FLIE total score (112.7 vs 108.6, p control in the MEC/AC study (73.2 vs 67.4, p = 0.027).
CONCLUSIONS: Compared with control, rolapitant improved quality of life in patients receiving HEC or MEC.
METHODS: Sprague-Dawley female rats (12 weeks old) were divided randomly into five groups (n = 6): healthy; nontreated OA; OA + diclofenac (5 mg/kg); OA + extract (200 mg/kg); and OA + extract (400 mg/kg). Two weeks after bilaterally ovariectomy, OA was induced by intra-articular injection of monosodium iodoacetate into the right knee joints. After 28 days of treatment, the rats were evaluated for knee OA via physical (radiological and histological observations), biochemical, enzyme-linked immunosorbent assay, and gene expression analysis, for inflammation and cartilage degradation biomarkers.
RESULTS: The osteoarthritic rats treated with the extract, and diclofenac showed significant reduction of cartilage erosion (via radiological, macroscopic, and histological images) compared with untreated osteoarthritic rats. The elevated serum interleukin-1β, prostaglandin E2, and C-telopeptide type II collagen levels in osteoarthritic rats were significantly reduced by F deltoidea leaf extract comparable to diclofenac. The extract significantly down-regulated the interleukin-1β, prostaglandin E2 receptor, and matrix metalloproteinase-1 mRNA expressions in the osteoarthritic cartilages, similar to diclofenac.
CONCLUSIONS: F deltoidea leaf extract mitigated postmenopausal osteoarthritic joint destruction by inhibiting inflammation and cartilage degradation enzymes, at an effective extract dose equivalent to about 60 mg/kg for humans. The main bioactive compounds are probably the antioxidative flavonoids vitexin and isovitexin.
METHODS: Male Wistar rats (200-250 g) were divided into 4 groups according to the diet given: control group (normal diet), ChV group with three different doses (50, 150 and 300 mg/kg body weight), liver cancer- induced group (choline deficient diet + 0.1% ethionine in drinking water or CDE group), and the treatment group (CDE group treated with three different doses of ChV). Rats were killed at 0, 4, 8 and 12 weeks of experiment and blood and tissue samples were taken from all groups for the determination of tumour markers expression alpha-fetoprotein (AFP), transforming growth factor-β (TGF-β), M2-pyruvate kinase (M2-PK) and specific antigen for oval cells (OV-6).
RESULTS: Serum level of TGF-β increased significantly (p < 0.05) in CDE rats. However, ChV at all doses managed to decrease (p < 0.05) its levels to control values. Expressions of liver tumour markers AFP, TGF-β, M2-PK and OV-6 were significantly higher (p < 0.05) in tissues of CDE rats when compared to control showing an increased number of cancer cells during hepatocarcinogenesis. ChV at all doses reduced their expressions significantly (p < 0.05).
CONCLUSIONS: Chlorella vulgaris has chemopreventive effect by downregulating the expression of tumour markers M2-PK, OV-6, AFP and TGF-β, in HCC-induced rats.
METHODS: Over a one or two-year period, children <5 years hospitalized with CAP were identified using ICD-10 discharge codes. Cases were matched to standardized definitions of suspected (S-CAP), confirmed (C-CAP), or bacterial CAP (B-CAP) used in a pneumococcal conjugate vaccine efficacy study (COMPAS). Median total direct medical costs of CAP-related hospitalizations were calculated.
RESULTS: Vietnam (three centers): 7591 CAP episodes were identified with 4.3% (95% confidence interval 4.2;4.4) S-CAP, 3.3% (3.2;3.4) C-CAP and 1.4% (1.3;1.4) B-CAP episodes of all-cause hospitalization in children aged <5 years. The B-CAP case fatality rate (CFR) was 1.3%. Malaysia (two centers): 1027 CAP episodes were identified with 2.7% (2.6;2.9); 2.6% (2.4;2.8); 0.04% (0.04;0.1) due to S-CAP, C-CAP, and B-CAP, respectively. One child with B-CAP died. Indonesia (one center): 960 CAP episodes identified with 18.0% (17.0;19.1); 16.8% (15.8;17.9); 0.3% (0.2;0.4) due to S-CAP, C-CAP, and B-CAP, respectively. The B-CAP CFR was 20%. Korea (three centers): 3151 CAP episodes were identified with 21.1% (20.4;21.7); 11.8% (11.2;12.3); 2.4% (2.1;2.7) due to S-CAP, C-CAP, and B-CAP, respectively. There were no deaths.
COSTS: CAP-related hospitalization costs were highest for B-CAP episodes: 145.00 (Vietnam) to 1013.3 USD (Korea) per episode.
CONCLUSION: CAP hospitalization causes an important health and cost burden in all four countries studied (NMRR-12-50-10793).
METHODS: Patients from TREAT Asia HIV Observational Database (September 2015 data transfer) aged 18 years and older with a CD4 count <50 cells/mm at ART initiation were included. The effect of macrolide prophylaxis on HIV-associated mortality or AIDS-defining conditions (as a combined outcome) and HIV-associated mortality alone were evaluated using competing risk regression. Sensitivity analysis was conducted in patients with a CD4 <100 cells/mm at ART initiation.
RESULTS: Of 1345 eligible patients, 10.6% received macrolide prophylaxis. The rate of the combined outcome was 7.35 [95% confidence interval (CI): 6.04 to 8.95] per 100 patient-years, whereas the rate of HIV-associated mortality was 3.14 (95% CI: 2.35 to 4.19) per 100 patient-years. Macrolide use was associated with a significantly decreased risk of HIV-associated mortality (hazard ratio 0.10, 95% CI: 0.01 to 0.80, P = 0.031) but not with the combined outcome (hazard ratio 0.86, 95% CI: 0.32 to 2.229, P = 0.764). Sensitivity analyses showed consistent results among patients with a CD4 <100 cells/mm at ART initiation.
CONCLUSIONS: Macrolide prophylaxis is associated with improved survival among Asian HIV-infected patients with low CD4 cell counts and on ART. This study suggests the increased usage and coverage of macrolide prophylaxis among people living with HIV in Asia.
