Roles of superabsorbent polymers (SAPs) and palm oil fuel ash (POFA) on the strength, cost analysis and CO emission of lightweight concrete: Comparison with aluminum-based aerated concrete.

This work investigated the effects of superabsorbent polymers (SAPs) as pore-forming agent and palm oil fuel ash (POFA) as sand replacement (0-100 % by weight) on the strength, economic feasibility, and CO emissions for lightweight concrete production. The product properties were compared with the traditional aerated concrete (with aluminum powder), which aimed to shed light on the use of SAPs and POFA for manufacturing a more sustainable lightweight concrete. The use of POFA to replace sand increased the cost of production by approximately 1-7% and CO emissions by approximately 3-12 % due primarily to the transportation of the POFA from the oil palm fuel power plant, which could be avoided if produced on site of or near the power plant.

Background: This animal study sought to evaluate two novel nanomaterials for pulpotomy of primary teeth and assess the short-term pulpal response and hard tissue formation in dogs. The results were compared with mineral trioxide aggregate (MTA).
Methods: This in vivo animal study on dogs evaluated 48 primary premolar teeth of 4 mongrel female dogs the age of 6-8 weeks, randomly divided into four groups (n = 12).
Tonsillectomy compared with conservative management in patients over 16 years with recurrent sore throat: the NATTINA RCT and economic evaluation.

Article Synopsis
- * Conducted across 27 NHS hospitals in Great Britain, the trial randomly assigned 453 participants to either undergo tonsillectomy or receive conservative care, focusing on tracking various outcomes related to sore throat symptoms.
- * Key objectives included measuring total sore throat days over 24 months, assessing the severity and impact of episodes on daily life, and analyzing economic factors like cost per sore throat day avoided and quality-adjusted life years gained.
Conservative management versus tonsillectomy in adults with recurrent acute tonsillitis in the UK (NATTINA): a multicentre, open-label, randomised controlled trial.

Population Health Sciences Institute, Newcastle University, Newcastle upon Tyne, UK.
Background: Tonsillectomy is regularly performed in adults with acute tonsillitis, but with scarce evidence. A reduction in tonsillectomies has coincided with an increase in acute adult hospitalisation for tonsillitis complications. We aimed to assess the clinical effectiveness and cost-effectiveness of conservative management versus tonsillectomy in patients with recurrent acute tonsillitis.
