“…The median WTP rates per parent groups for their self-vaccination were US$86.96 and US$156.52, and for their children’s vaccination were US$108.70 and US$195.65, respectively for Types 1 and 2 DV (Figure 4). The findings from this study suggest very high estimates compared to those reported in previous studies 15–17,42,43. The latest study in Vietnam15 estimated the median WTP rate per household at US$26.4 for three doses (around US$32.25 in 2018).…”

BackgroundDengue was endemic to Vietnam. Due to the lack of a readily available remedy, dengue vaccines (DV) have been used elsewhere to cure the disease. However, introducing DV in Vietnam has met resistance from society and the government, influencing decisions about willingness-to-pay (WTP) and other pharmacoeconomic studies. This research aimed to evaluate the extent to which Vietnamese customers would be willing to pay to vaccinate themselves and their children, if any at all, against dengue.Materials and methodsThis was a cross-sectional interview-based research. Contingent valuation method, combined with the bidding technique and several open-ended questions, were used to obtain the maximum WTP values for six hypothetical scenarios of two types of DV (60% efficacy for 10 years, “Type 1” vs 90% efficacy for 20 years, “Type 2”).ResultsThe median WTP per adult for Type 1 and Type 2 DV were US$130.34 and US$217.39, respectively. The median WTP rates per parent for their own vaccination were US$86.96 (Type 1) and US$156.52 (Type 2), for their children vaccination costs were US$108.70 (Type 1) and US$195.65 (Type 2). Five factors affected the WTP rates: monthly income, marital status, area, locality and level of education.ConclusionThe WTP rates for DV were high, supporting the introduction of DV in Vietnam.

“…In effort to reach this goal, we collected several studies from PubMed and Embase concerning this association to calculate a poolled odd ratio (OR) and 95% confidence interval (CI) using fixed or random effect model. This design of the study was adapted from our previous meta-analysis 51, 52, 53, 54, 55…”

ObjectiveTo investigate the no reflow risk factors after percutaneous coronary intervention in ST elevation myocardial infarction patients.MethodSample size, mean ± standard deviation (SD) or frequencies (percent) of normal and no reflow groups were extracted from each study.ResultsOf 27 retrospective and prospective studies, we found that increasing risks of no reflow were associated with advanced age, male, family history of coronary artery disease, smoking, diabetes mellitus, hypertension, delayed reperfusion, killip class ≥2, elevated blood glucose, increased creatinine, elevated creatine kinase (CK), higher heart rate, decreased left ventricular ejection fraction (LVEF), collateral flow ≤1, longer lesion length, multivessel disease, reference luminal diameter, initial thrombolysis in myocardial infarction (TIMI) flow, and high thrombus burden. Moreover, initial TIMI flow ≤1 and high thrombus burden had the greater impact on no reflow (OR95%CI = 3.83 [2.77–5.29], p < 0.0001 and 3.69 [2.39–5.68], p < 0.0001, respectively).ConclusionOur meta-analysis reveals that initial TIMI flow ≤1 and high thrombus burden are the most impacted no reflow risk factors.

“…To reach this goal, several studies regarding the association between hip geometry and femoral neck fractures were collected for calculating combined odds ratios and 95% confidence intervals (ORs 95% CI) and assessed using fixed or random effect model. The design was adapted from our previous studies [20] , [21] , [22] , [23] , [24] . Articles were searched in PubMed and Embase.…”

BackgroundSeveral studies have reported hip geometry to predict the femoral neck fractures. However, they showed inconsistency.ObjectivesTo determine the association between hip geometry and femoral neck fractures.MethodsPublished literature from PubMed and Embase databases (until May 25th, 2017) was searched for eligible publications. The information related to (1) name of first author; (2) year of publication; (3) country of origin; (4) sample size of cases and controls and (5) mean and standard deviation of cases and controls were extracted. The pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association between hip geometry and femoral neck fractures were assessed using random or fixed effect model. A Comprehensive Meta-analysis software, version 2.0, was used to analyse the data.ResultsA total of 11 studies were included in this study. Our results showed that increase in hip axis length (OR 95% CI = 1.53 [1.06–2.21], p = 0.025), femoral neck angle (OR 95% CI = 1.47 [1.01–2.15], p = 0.044) and neck width (OR 95% CI = 2.68 [1.84–3.91], p < 0.001) was associated with the risk of femoral neck fractures, whereas we could not find the correlation between femoral neck axis length and the risk of femoral neck fractures.ConclusionThere is strong evidence that elevated hip axis length, femoral neck angle and neck width are the risk factor for femoral neck fractures.The Translational Potential of this Article: Determining the hip axis length, femoral neck angle and neck width that are most highly associated with femoral neck fracture may allow clinicians to more accurately predict which individuals are likely to experience femoral neck fractures in the future.
