BackgroundOf the 140 000 Burmese* refugees living in camps in Thailand, 30% are youths aged 15-24. Health services in these camps do not specifically target young people and their problems and needs are poorly understood. This study aimed to assess their reproductive health issues and quality of life, and identifies appropriate service needs.MethodsWe used a stratified two-stage random sample questionnaire survey of 397 young people 15-24 years from 5,183 households, and 19 semi-structured qualitative interviews to assess and explore health and quality of life issues.ResultsThe young people in the camps had very limited knowledge of reproductive health issues; only about one in five correctly answered at least one question on reproductive health. They were clear that they wanted more reproductive health education and services, to be provided by health workers rather than parents or teachers who were not able to give them the information they needed. Marital status was associated with sexual health knowledge; having relevant knowledge of reproductive health was up to six times higher in married compared to unmarried youth, after adjusting for socio-economic and demographic factors. Although condom use was considered important, in practice a large proportion of respondents felt too embarrassed to use them. There was a contradiction between moral views and actual behaviour; more than half believed they should remain virgins until marriage, while over half of the youth experienced sex before marriage. Two thirds of women were married before the age of 18, but two third felt they did not marry at the right age. Forced sex was considered acceptable by one in three youth. The youth considered their quality of life to be poor and limited due to confinement in the camps, the limited work opportunities, the aid dependency, the unclear future and the boredom and unhappiness they face.ConclusionsThe long conflict in Myanmar and the resultant long stay in refugee camps over decades affect the wellbeing of these young people. Lack of sexual health education and relevant services, and their concerns for their future are particular problems, which need to be addressed. Issues of education, vocational training and job possibilities also need to be considered.*Burmese is used for all ethnic groups
Background: Several treatment options for cold urticaria (ColdU) have been studied and reported, but systematic reviews and meta-analyses are limited. Objectives: We sought to meta-analyze and review the efficacy and safety of ColdU treatments. Methods: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Suitable reports were identified by searching PubMed, Scopus, and Web of Science. Our systematic review included 16 studies, 9 of which met the eligibility criteria for the meta-analysis. We analyzed the effects of treatments on critical temperature thresholds (CTTs) and critical stimulation time thresholds (CSTTs), as well as on rates of complete response and adverse events. Results: Our pooled meta-analyses showed that nonsedating second-generation H 1 -antihistamines (nsAHs) are effective in the treatment of ColdU and that updosing of nsAHs significantly reduced CTTs relative to their own standard doses and placebos. In 4 studies involving CSTTs, updosing of nsAHs also resulted in significantly better CSTTs than their own standard doses or placebos. Omalizumab resulted in a marked reduction of CTTs in H 1 -antihistamine-resistant patients. Of 118 adverse events in 8 studies, standard-dose nsAHs, updosed nsAHs, and omalizumab produced lower numbers of adverse events than first-generation antihistamines. Conclusions: Our study showed that greater dosages of nsAHs were more effective than standard dosages in controlling ColdU symptoms. Increasing the dosages was not significantly associated with higher adverse event rates. Omalizumab at 150 and 300 mg every 4 weeks was shown to be effective for patients with ColdU refractory to antihistamines.
IntroductionThai pharmacy education consists of two undergraduate programs, a 5-year Bachelor of Science in Pharmacy (BScPsci and BScPcare) degree and a 6-year Doctor of Pharmacy (Pharm D). Pharmacy students who wish to serve in the public sector need to enroll in the public service program. This study aims to compare the perception of professional competency among new pharmacy graduates from the three different pharmacy programs available in 2013 who enrolled in the public service program.MethodsA cross-sectional survey was conducted among new pharmacy graduates in 2013 using a self-administered, structured, close-ended questionnaire. The questionnaire consisted of respondents’ characteristics and perception of professional competencies. The competency questions consisted of 13 items with a 5-point scale. Data collection was conducted during Thailand’s annual health professional meeting on April 2, 2013 for workplace selection of pharmacy graduates.ResultsA total of 266 new pharmacy graduates responded to the questionnaire (response rate 49.6%). There were no significant differences in sex and admission modes across the three pharmacy programs. Pharm D graduates reported highest competency in acute care services, medication reconciliation services, and primary care services among the other two programs. BScPsci graduates reported more competence in consumer health protection and herbal and alternative medicines than BScPcare graduates. There were significant differences in three competency domains: patient care, consumer protection and community health services, and drug review and information, but no significant differences in the health administration and communication domain among three pharmacy programs.ConclusionDespite a complete change into a 6-year Pharm D program in 2014, pharmacy education in Thailand should continue evolving to be responsive to the needs of the health system. An annual survey of new pharmacy graduates should be continued, to monitor changes of professional competency across different program tracks and other factors which may influence their contribution to the health service system. Likewise, a longitudinal monitoring of their competencies in the graduate cohort should be conducted.
Background Nonvalvular atrial fibrillation (AF) is the most common cardiac arrhythmia, and it is associated with the prothrombotic state. Circulating microparticles (cMPs) are membrane vesicles that are shed from many cell types in response to cell activation and cell apoptosis. Several studies reported that cMPs may play a role in the hypercoagulable state that can be observed in patients with AF. The aim of this study was to determine the levels of total cMPs and characterize their cellular origins in AF patients. Methods Atotal of 66 AF patients and 33 healthy controls were enrolled. This study investigated total cMP levels and their cellular origin in AF patients using polychromatic flow cytometry. Results AF patients had significantly higher levels of total cMPs (median 36.38, interquartile range [IQR] 21.16‐68.50 × 10 5 counts/mL vs median 15.21, IQR 9.91‐30.86 × 10 5 counts/mL; P = 0.004), platelet‐derived MPs (PMPs) (median 10.61, IQR 6.55‐18.04 × 10 5 counts/mL vs median 7.83, IQR 4.44‐10.26 × 10/mL; P = 0.009), and endothelial‐derived MPs (EMPs CD31+ CD41−) (median 2.94, IQR 1.78‐0.60 × 10 5 counts/mL vs median 1.16, IQR 0.71‐2.30 × 10 5 counts/mL; P = 0.001) than healthy controls after adjusting for potential confounders. Phosphatidylserine positive MP (PS + MP) levels were similar compared between AF patients and healthy controls. Conclusion The results of this study revealed a marked increase in total cMP levels, and evidence of elevated endothelial damage and platelet activation, as demonstrated by increased PMP and EMP levels, in AF patients. Additional study is needed to further elucidate the role of cMPs (PMPs and EMPs) in the pathophysiology of and the complications associated with AF.
Background Dengue is the most significant mosquito-borne viral disease; there are no specific therapeutics. The antiparasitic drug ivermectin efficiently inhibits the replication of all 4 dengue virus serotypes in vitro. Methods We conducted 2 consecutive randomized, double-blind, placebo-controlled trials in adult dengue patients to evaluate safety and virological and clinical efficacies of ivermectin. After a phase 2 trial with 2 or 3 days of 1 daily dose of 400 µg/kg ivermectin, we continued with a phase 3, placebo-controlled trial with 3 days of 400 µg/kg ivermectin. Results The phase 2 trial showed a trend in reduction of plasma nonstructural protein 1 (NS1) clearance time in the 3-day ivermectin group compared with placebo. Combining phase 2 and 3 trials, 203 patients were included in the intention to treat analysis (100 and 103 patients receiving ivermectin and placebo, respectively). Dengue hemorrhagic fever occurred in 24 (24.0%) of ivermectin-treated patients and 32 (31.1%) patients receiving placebo (P = .260). The median (95% confidence interval [CI]) clearance time of NS1 antigenemia was shorter in the ivermectin group (71.5 [95% CI 59.9–84.0] hours vs 95.8 [95% CI 83.9–120.0] hours, P = .014). At discharge, 72.0% and 47.6% of patients in the ivermectin and placebo groups, respectively had undetectable plasma NS1 (P = .001). There were no differences in the viremia clearance time and incidence of adverse events between the 2 groups. Conclusions A 3-day 1 daily dose of 400 µg/kg oral ivermectin was safe and accelerated NS1 antigenemia clearance in dengue patients. However, clinical efficacy of ivermectin was not observed at this dosage regimen.
Objective. To determine whether key features of systemic lupus erythematosus (SLE), namely, production of non-nuclear antibodies (anti-C1q and anticardiolipin antibodies [aCL]) and depletion of complement components C3 and C4, aggregate in families. In addition, we examined relationships between anti-C1q and C3 and C4 levels.Methods. The study cohort comprised 1,037 predominantly white (82%) nuclear families in which at least 1 member had SLE. Associations of antibody measurements between probands and their unaffected siblings were examined using parametric and nonparametric analyses, along with associations between unaffected siblings and their parents. The heritability of anti-C1q, C3, and C4 was estimated, and interdependencies between these factors were examined in a regression model accounting for the family structure of the data set.Results We also demonstrated significant heritability of anti-C1q, C3, and C4 (ϳ45%). Anti-C1q was negatively associated with C3 and C4 in SLE probands but not in their healthy relatives.Conclusion. Non-nuclear antibodies and C3 and C4 cluster within the families of SLE probands, suggesting that specific autoantibody formation is partly genetically determined, even if the total genetic effect in unaffected relatives is insufficient to cause disease. Anti-C1q antibodies accelerate C3 and C4 depletion in patients with SLE but have no effect in the absence of disease.Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by immune-mediated damage to multiple organ systems. Studies have shown a concordance rate of 24-57% in monozygotic twins compared with 2-5% in dizygotic twins and a sibling risk ratio ( s ) of 20-29 (1-4). There is, therefore, evidence for a strong genetic component to SLE, although the overall etiology is likely to depend on a complex interaction of genetic and environmental factors.The classic autoantibodies in patients with SLE are those directed at nuclear antigens; however, antibodies directed against non-nuclear targets also play an Drs.
Clopidogrel is an antiplatelet prodrug that is recommended to reduce the risk of recurrent thrombosis in coronary artery disease (CAD) patients. Paraoxonase 1 (PON1) is suggested to be a rate-limiting enzyme in the conversion of 2-oxo-clopidogrel to active thiol metabolite with inconsistent results. Here, we sought to determine the associations of CYP2C19 and PON1 gene polymorphisms with clopidogrel response and their role in ADP-induced platelet aggregation. Clopidogrel response and platelet aggregation were determined using Multiplate aggregometer in 211 patients with established CAD who received 75 mg clopidogrel and 75–325 mg aspirin daily for at least 14 days. Polymorphisms in CYP2C19 and PON1 were genotyped and tested for association with clopidogrel resistance. Linkage disequilibrium (LD) and their epistatic interaction effects on ADP-induced platelet aggregation were analysed. The prevalence of clopidogrel resistance in this population was approximately 33.2% (n = 70). The frequencies of CYP2C19*2 and *3 were significantly higher in non-responder than those in responders. After adjusting for established risk factors, CYP2C19*2 and *3 alleles independently increased the risk of clopidogrel resistance with adjusted ORs 2.94 (95%CI, 1.65–5.26; p<0.001) and 11.26 (95%CI, 2.47–51.41; p = 0.002, respectively). Patients with *2 or *3 allele and combined with smoking, diabetes and increased platelet count had markedly increased risk of clopidogrel resistance. No association was observed between PON1 Q192R and clopidogrel resistance (adjusted OR = 1.13, 95%CI, 0.70–1.82; p = 0.622). Significantly higher platelet aggregation values were found in CYP2C19*2 and *3 patients when compared with *1/*1 allele carriers (p = 1.98×10−6). For PON1 Q192R genotypes, aggregation values were similar across all genotype groups (p = 0.359). There was no evidence of gene-gene interaction or LD between CYP2C19 and PON1 polymorphisms on ADP-induced platelet aggregation. Our findings indicated that only CYP2C19*2 and *3 alleles had an influence on clopidogrel resistance. The risk of clopidogrel resistance increased further with smoking, diabetes, and increased platelet count.
