Effect of Standard Treatment Guidelines with or without Prescription Audit on Prescribing for Acute Respiratory Tract Infection (ARI) and Diarrhoea in some Thana Health Complexes (THCs) of Bangladesh

Inappropriate prescribing for ARI and diarrhoea is a serious health problem in many developing countries including Bangladesh. A baseline retrospective prescribing survey for ARI and diarrhoea have been conducted in randomly selected 60 thana health complexes (THCs) of Dhaka division of Bangladesh. In the 38 of 60 THCs, the prescribers did not comply with the standard treatment guidelines (STG) for ARI. They are marked as \u27unsatisfactory performers\u27. In these THCs unnecessary antibiotics were prescribed in more than 50% of the encounters. The study further revealed that in 26 THCs, comprising 41.6% of the 38 THCs, the situation was even worse regarding the indiscriminate use of antibiotics. In these THCs antibiotics were prescribed in \u3e or =72% of the encounters. For diarrhoea, only in 8.3% of the THCs antibiotics were prescribed in \u3e or =50% of the encounters. Encouragingly, most of the prescribers prescribed ORS. So the diarrhoea cases were dropped from the intervention. The 24 out of 26 worse performing THCs for ARI management, were grouped into three groups: Group-I (implementing STG+ Audit), Group-II (STG) and Group-III (no intervention, control). The prescribers of the THCs belonging to Group-I and Group-II received STG+Audit and STG only respectively as intervention(s). On the contrary, the prescribers of the THCs of Group-III (control) did not receive any intervention. It was observed that after the implementation of interventions the use of the unnecessary antibiotics to treat ARI was significantly reduced (p\u3c0.01) compared to pre-intervention period in Group-I (STG+Audit). In this group highly significant (p\u3c0.000) reduction in antibiotics use was achieved in 6 out of 8 THCs. The average reduction in antibiotic use in terms of encounters was 23.7 and 15.2% in the Group-I and Group-II respectively owing to the intervention(s). Significant reduction in antibiotic use in terms of THCs was 3 (out of 8 THCs) and 2 (out of 8 THCs) belonging to the Group-II and Group-III respectively. When compensated for the change in the control group, the reduction of antibiotic use in terms of encounters was 15.2 and 6.9% in the THCs of the Group-I and Group-II respectively due to introduction of the interventions. The study concludes that STG supported by prescription audit are highly effective interventions to change the prescribing behaviour of the prescribers for ARI in the THCs

Numerical analysis of thermofluids inside a porous enclosure with partially heated wall

In this study, heat transfer in a tall, rectangular permeable cavity with active thermal walls is investigated. Inside the enclosure, the two side walls' central portions are partially cooled at a fixed temperature. The central portion of the footwall is heated. Additionally, the top wall, the remaining portion of the footwall, and the side walls are insulated. The controlling equations are obtained from the Brinkman–Forchheimer-extended Darcy prototypical model using Boussinesq calculations. The leading equations are explained numerically by the finite element Galerkin method of weighted residuals. The computations are executed for some governing and physical parameters. The isotherms, streamlines and average heat transfer rate along with the partially active hot wall are shown for different groupings of governing parameters with respect to dimensionless time (τ). The outcomes indicated that the stream and thermal fields are strongly dependent on the considered parameters. It is also established that the average heat transfer rate is a function of these governing parameters

Data from: Bt eggplant (Solanum melongena L.) in Bangladesh: Fruit production and control of eggplant fruit and shoot borer (Leucinodes orbonalis Guenee), effects on non-target arthropods and economic returns

Eggplant or brinjal (Solanum melongena) is a popular vegetable grown throughout Asia where it is attacked by brinjal fruit and shoot borer (BFSB) (Leucinodes orbonalis). Yield losses in Bangladesh have been reported up to 86% and farmers rely primarily on frequent insecticide applications to reduce injury. Bangladesh has developed and released four brinjal varieties producing Cry1Ac (Bt brinjal) and is the first country to do so. We report on the first replicated field trials comparing four Bt brinjal varieties to their non-Bt isolines, with and without standard insecticide spray regimes. Results of the two-year study (2016-17) indicated Bt varieties had increased fruit production and minimal BFSB fruit infestation compared with their respective non-Bt isolines. Fruit infestation for Bt varieties varied from 0-2.27% in 2016, 0% in 2017, and was not significantly affected by the spray regime in either year. In contrast, fruit infestation in non-Bt lines reached 36.70% in 2016 and 45.51% in 2017, even with weekly spraying. An economic analysis revealed that all Bt lines had higher gross returns than their non-Bt isolines. The non-sprayed non-Bt isolines resulted in negative returns in most cases. Maximum fruit yield was obtained from sprayed plots compared to non-sprayed plots, indicating that other insects such as whiteflies, thrips and mites can reduce plant vigor and subsequent fruit weight. Statistically similar densities of non-target arthropods, including beneficial arthropods, were generally observed in both Bt and non-Bt varieties. An additional trial that focused on a single Bt variety and its isoline provided similar results on infestation levels, with and without sprays, and similarly demonstrated higher gross returns and no significant effects on non-target arthropods. Together, these studies indicate that the four Bt brinjal lines are extremely effective at controlling BFSB in Bangladesh without affecting other arthropods, and provide greater economic returns than their non-Bt isolines
