ABSTRACT

BACKGROUND: A core element of the Strengthening Responses to Dementia in Developing Countries (STRiDE) programme was to generate novel data on the prevalence, cost and impact of dementia in low- and middle-income countries, to build better health policy. Indonesia and South Africa are two middle-income countries in need of such data.

AIMS: To present the STRiDE methodology and generate estimates of dementia prevalence in Indonesia and South Africa.

METHOD: We conducted community-based, single-phase, cross-sectional studies in Indonesia and South Africa, randomly sampling participants aged 65 years or older in each country. Dementia prevalence rates for each country were generated by using the 10/66 short schedule and applying its diagnostic algorithm. Weighted estimates were calculated with national sociodemographic data.

RESULTS: Data were collected between September and December 2021 in 2110 people in Indonesia and 408 people in South Africa. The adjusted weighted dementia prevalence was 27.9% (95% CI 25.2-28.9) in Indonesia and 12.5% (95% CI 9.5-16.0) in South Africa. Our results indicate that there could be >4.2 million people in Indonesia and >450 000 people in South Africa who have dementia. Only five participants (0.2%) in Indonesia and two (0.5%) in South Africa had been previously diagnosed with dementia.

CONCLUSIONS: Despite prevalence estimates being high, formal diagnosis rates of dementia were very low across both countries (<1%). Further STRiDE investigations will provide indications of the impact and costs of dementia in these countries, but our results provide evidence that dementia needs to be prioritised within national health and social care policy agendas.

ABSTRACT

The present study evaluated the reproductive compatibility of Trichogramma pretiosum Riley, 1879, through an integrative approach using biological data and morphometry of three isofemale lines (isolines) collected from two geographical areas. These isolines differed in sequences of mitochondrial DNA and reproductive performance in the laboratory. The wasps used to initiate the isolines were collected in different environments: two lines from a Mediterranean climate in Irvine, California, USA, and one line from a tropical climate in Piracicaba, São Paulo, Brazil. Reproductive compatibility was studied by evaluating the sex ratio and number of adult offspring produced of all mating combinations between adults from these isolines. Morphometry was studied by measuring 26 taxonomically useful characters, followed by a multivariate analysis. For the allopatric matings among Brazilian and North American isolines, a low level of crossing incompatibility was recorded, in only one direction of the crosses; whereas the sympatric North American isolines were incompatible in both directions. Multivariate analysis of the morphometric data indicated no distinct groups, suggesting that despite the genetic and biological differences, the isofemale lines are morphologically similar.

ABSTRACT

INTRODUCTION: Neuromuscular warm-up programs, such as FIFA 11+ were developed as early as 2006. These programs have been effective in reducing the risk of injury in female athletes by decreasing the moments surrounding the knee and improving neuromuscular control during static and dynamic movements such as jumping and landing. In addition, they have been effective for improving jump height in soccer, volleyball, and basketball.

METHODS: The effects of the 11+ Dance, a dance-specific neuromuscular warm-up program, was examined on jump height and lower extremity biomechanics during bilateral and single leg countermovement jumps in recreational dancers. Twenty female adolescents from 2 dance schools participated in this 2-centered 8-week controlled non-randomized trial. The intervention group (IG) performed the 11+ Dance program 3×/week for 8-weeks during the first 30-minute of their regularly scheduled dance classes. The control group (CG) continued with their regular dance classes routine. Ground reaction force and motion capture data were used to assess jump height and lower extremity biomechanics pre and post intervention.

RESULTS: Both groups statistically increased their jump height (CG: Z = 1.89-2.45, P ≤ .0167; IG: Z = 2.18-2.76, P ≤ .0167). However, no statistical between group differences were observed (Z = 0.38-1.22, P > .05). During takeoff, the IG statistically reduced peak knee extension moments (t(18) = -3.04 to -3.77, P ≤ .0167) while increasing peak hip extension moments (t(18) = 2.16-2.79, P ≤ .05) and peak hip flexion angles (t(18) = 2.68-3.72, P ≤ .0167) compared to the CG. The IG also increased the hip flexion angles compared to the CG during landing (t(18) = 2.78-5.13, P ≤ .0167) while no systematic differences were observed in all other variables of lower extremity biomechanics.

CONCLUSION: The reduced joint load at the knee observed during takeoff needs further investigation. Neuromuscular training, such as the 11+ Dance, is supported by numerous quality research. Due to its simplicity, the 11+ Dance may be feasible and beneficial to complement regular warm-ups in recreational dance practice.

ABSTRACT

Receiver operating characteristic analysis is one of the most popular approaches for evaluating and comparing the accuracy of medical diagnostic tests. Although various methodologies have been developed for estimating receiver operating characteristic curves and their associated summary indices, there is no consensus on a single framework that can provide consistent statistical inference while handling the complexities associated with medical data. Such complexities might include non-normal data, covariates that influence the diagnostic potential of a test, ordinal biomarkers or censored data due to instrument detection limits. We propose a regression model for the transformed test results which exploits the invariance of receiver operating characteristic curves to monotonic transformations and accommodates these features. Simulation studies show that the estimates based on transformation models are unbiased and yield coverage at nominal levels. The methodology is applied to a cross-sectional study of metabolic syndrome where we investigate the covariate-specific performance of weight-to-height ratio as a non-invasive diagnostic test. Software implementations for all the methods described in the article are provided in the tram add-on package to the R system for statistical computing and graphics.

ABSTRACT

The common terminology criteria for adverse events by the National Cancer Institute has greatly facilitated the revolution of drug development and an increasing number of Phase I trials have started to collect multiple-grade toxicity endpoints. Appropriate and yet transparent Phase I statistical designs for multiple-grade toxicities are therefore in great needs. In this article, we propose a quasi-toxicity probability interval (qTPI) design that incorporates a quasi-continuous measure of the toxicity probability ($qTP$) into the Bayesian theoretic framework of the interval based designs. Multiple-grade toxicity outcomes of each patient are mapped to $qTP$ according to a severity weight matrix. Dose-toxicity curve underlying the dosing decisions in the qTPI design is continuously updated using accumulating trial data. Numerical simulations investigating the operating characteristics of qTPI show that qTPI achieved better safety, accuracy and reliability compared to designs that rely on binary toxicity data. Furthermore, parameter elicitation in qTPI is simple and does not involve multiple hypothetical cohorts specification. Finally, a hypothetical soft tissue sarcoma trial with six toxicity types and grade 0 to grade 4 severity grades is illustrated with patient-by-patient dose allocation under the qTPI design.

ABSTRACT

Statistical sequential analysis of binary data is an important tool in clinical trials such as placebo-controlled trials, where a total of $K$ individuals are randomly allocated into two groups, one of size ${\kappa }_1$ receiving the treatment/drug, and the other of size ${\kappa }_2$ for placebo. The ratio $z={\kappa }_2/{\kappa }_1$, namely “matching ratio,” determines the expected proportion of adverse events from the treatment group among the ${\kappa }_1+{\kappa }_2$ individuals. Bernoulli-based designs are used for monitoring the safety of post-licensed drugs and vaccines as well. For instance, in a self-control design, $z$ is the ratio between the risk and the control time windows. Irrespective of the type of application, the choice of $z$ is a critical design criterion as it determines the sample size, the statistical power, the expected sample size, and the expected time to signal the sequential procedure. In this paper, we run exact calculations to offer a statistical rule of thumb for the choice of $z$. All the calculations and examples are performed using the R Sequential package.

ABSTRACT

Objective: To assess the clinical value of bedaquiline in five dimensions: effectiveness, safety, economics, appropriateness, and social benefits, to provide a reference for medical and health insurance-related decisions. Methods: A total of 792 patients with multidrug-resistant tuberculosis who were hospitalized at Wuhan Pulmonary Hospital, Ganzhou Fifth People’s Hospital and Jiangxi Chest Hospital between January 2018 and December 2020 were included in the study. Based on a retrospective survey of case data, and each evaluation dimension of bedaquiline was statistically analyzed by causal analysis or chi-square test, using linezolid as the reference drug. Results: In terms of effectiveness, bedaquiline significantly increased treatment success by 23.9% (95%CI:4.8%-43.0%) and shortened treatment duration by 64 days(95%CI:18-109 days). In terms of safety, the incidence of adverse reactions to bedaquiline and the discontinuation rate of adverse reactions (5.11%,4.55%) were significantly lower than those for linezolid (22.49%,15.24%), with statistically significant differences (χ²=27.50,P<0.001;χ²=14.09,P<0.001). In terms of economics, patients treated with bedaquiline had a significantly higher anti-TB drug course cost of RMB 48 209.4 Yuan(95%CI: 28 336.0-68 082.8 Yuan). In terms of appropriateness, the proportion of bedaquiline in patients’ initial treatment regimens was lower than that of linezolid (16.7% vs. 86.5%) in the 2020 observation sample, with a statistically significant difference (χ²=238.96,P<0.001). In terms of social benefits, the infection control rate was significantly increased by 27.8% (95%CI:8.2%-47.5%) in patients using bedaquiline. Conclusions: Bedaquiline performed well in terms of efficacy, safety, and social benefits. However, it was less economical and the actual use rate of bedaquiline in clinical practice was lower than that of its counterpart drug, linezolid. Price reductions might be needed to increase the clinical use and performance of bedaquiline in the future.

ABSTRACT

OBJECTIVE: This study aims to adapt the English-language Hospital Anxiety and Depression Scale (HADS) to the Indonesian language and evaluate the validity and reliability of the adapted version (ie, HADS-Indonesia).

DESIGN: A cross-sectional study was conducted between June and November 2018. First, a translation and back-translation process was conducted by a committee consisting of the researchers, a psychiatrist, a methodology consultant and two translators. Face and convergent validity and test-retest reliability evaluations were conducted. Next, structural validity and internal consistency analyses were performed. An intraclass correlation coefficient (ICC) test evaluated the scale’s test-retest reliability. A Spearman’s rank correlation coefficient was calculated to evaluate the correlation between HADS-Indonesia and Zung’s Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) for convergent validity evidence. Next, a structural validity analysis using exploratory factor analysis (EFA) and an internal consistency evaluation based on Cronbach’s alpha was conducted.

SETTING: This study was conducted in three villages in Jatinangor subdistrict, Sumedang Regency, West Java province, Indonesia; the villages were chosen based on their profiles.

PARTICIPANTS: A total of 200 participants (male: n=91, 45.50% and female: n=109, 54.50%), with a mean age of 42.41 (14.25) years, were enrolled in this study using a convenience sampling method. The inclusion criteria were age ≥18 years old with basic Indonesian language literacy.

RESULTS: The overall HADS-Indonesia’s ICC value was 0.98. There was a significant positive correlation between HADS-Indonesia’s anxiety subscale and Zung’s SAS (r_s=0.45, p=0.030) and between the depression subscale of HADS-Indonesia and Zung’s SDS (r_s=0.58, p<0.001). The Kaiser-Meyer-Olkin statistics (KMO) (KMO=0.89) and Bartlett’s test of sphericity (χ²(91, N=200)=1052.38, p<0.001)) indicated an adequate number of samples for EFA. All items’ commonality was >0.40 and the average inter-item correlation was 0.36. EFA yielded a 2-factor solution explaining 50.80% (40.40%+10.40%) of the total variance. All items from the original HADS were retained, including its original subscales. The adapted HADS-Anxiety subscale consisted of seven items (alpha=0.85), and the HADS-Depression subscale consisted of seven items (alpha=0.80).

CONCLUSIONS: HADS-Indonesia is a valid and reliable instrument for use in the general population of Indonesia. However, further studies are warranted to provide more sophisticated validity and reliability evidence.
